7f3a19789c Batching - separate single item from large fvf logic
Trying to use the old `hardware_transform` flag to combine the new large_fvf has lead to several bugs. So here the logic is broken out into 2 separate components, single item and large_fvf.

The old `hardware_transform` name also no longer makes sense, as there are now 3 transform paths:

Software (CPU)
Hardware (uniform)
Hardware (attribute)

e2c28675ef Batch of lightmapper fixes and minor improvements
- Fix objects with no material being considered as fully transparent by the lightmapper.
- Added "environment_min_light" property: gives artistic control over the shadow color.
- Fixed "Custom Color" environment mode, it was ignored before.
- Added "interior" property to BakedLightmapData: controls whether dynamic capture objects receive environment light or not.
- Automatically update dynamic capture objects when the capture data changes (also works for "energy" which used to require object movement to trigger the update).
- Added "use_in_baked_light" property to GridMap: controls whether the GridMap will be included in BakedLightmap bakes.
- Set "flush zero" and "denormal zero" mode for SSE2 instructions in the Embree raycaster. According to Embree docs it should give a performance improvement.

5ed0fd067d Batching - use FINAL_MODULATE_ALIAS in shaders
As part of the improvements to batch more cases, batching can store final_modulate as an attribute in the vertex format rather than sending as a uniform. This allows draw calls with different final_modulate to be batched together.

However custom shader code was reading from only the final_modulate uniform, and not the attribute when it was in use. This was leading to visual errors.

This is tricky to solve, because we cannot use the same name for the attribute in the vertex and fragment shaders, because one is an attribute and one a varying, whereas a uniform is accessible anywhere. To get around this, a macro is used which can translate to the most appropriate variable depending on whether uniform or attribute or varying is required.

f24f582ba5 Various light culling fixes
GLES3 changes:
This commit makes it possible to disable 3D directional lights by using
the light's cull mask. It also automatically disables directionals when
the object has baked lighting and the light is set to "bake all".

GLES2 changes:
Added a check for the light cull mask, since it was previously ignored.

c401960634 Batching - fix custom MODULATE shader applying modulate twice
One of the new fvf types (FVF_MODULATED) allows batching custom shaders that use modulate. The only slight oversight is that there is a special define when MODULATE is used in a custom shader, called MODULATE_USED, that is checked, and if set it does NOT apply final_modulate as part of canvas.glsl.

This MODULATE_USED define wasn't checked when the new FVF was used and modulate was passed in an attribute.

This PR moves the application of the final_modulate into the #ifndef MODULATE_USED section.

b1e24597e7 Renaming rendering/2d project settings.
The rendering/quality/2d section of project settings is becoming considerably expanded in 3.2.4, and arguably was not the correct place for settings that were not really to do with quality.

3.2.4 is the last sensible opportunity we will have to move these settings, as the only existing one likely to break compatibility in a small way is `pixel_snap`, and given that the whole snapping area is being overhauled we can draw attention to the fact it has changed in the release notes.

Class reference is also updated and slightly improved.

`pixel_snap` is renamed to `gpu_pixel_snap` in the project settings and code to help differentiate from CPU side transform snapping.

3aaefb957b GLES2 fix for consistent light ordering with BVH
Due to multi pass approach to lighting in GLES2, in some situations the rendered result can look different if lights are presented in a different order.

The order (aside from directional lights) seems to be simply copied from the culling routine (octree or bvh) which is essentially arbitrary. While octree is usually consistent with order, bvh uses a trickle optimize which may result in lights occurring in different order from frame to frame.

This PR adds an extra layer of sorting on GLES2 lights in order to get some kind of order consistency.

Improve PCF13 shadow rendering in GLES2 by using a soft PCF filter
This suppresses the blocky shadow appearance, bringing the shadow rendering

The soft PCF filter was adapted from three.js.

565cfc888e Batching - fix a couple of minor valgrind bugs.
Valgrind reported two instances of reading uninitialized memory in the batching. They are both pretty benign (as evidenced by no bug reports) but wise to close these.

The first is that when changing batch from a default batch it reads the batch color which is not set (as it is not relevant for default batches). The segment of code is not necessary when it has already deemed a batch change necessary (which will occur from a default batch). In addition this means that the count of color changes will be more accurate, rather than having a possible random value in.

The second is that on initialization _set_texture_rect_mode is called before the state has been properly initialized (it is initialized at the beginning of each canvas_begin, but this occurs outside of that).

112b416056 Implement new CPU lightmapper
Completely re-write the lightmap generation code:
- Follow the general lightmapper code structure from 4.0.
- Use proper path tracing to compute the global illumination.
- Use atlassing to merge all lightmaps into a single texture (done by @RandomShaper)
- Use OpenImageDenoiser to improve the generated lightmaps.
- Take into account alpha transparency in material textures.
- Allow baking environment lighting.
- Add bicubic lightmap filtering.

There is some minor compatibility breakage in some properties and methods
in BakedLightmap, but lightmaps generated in previous engine versions
should work fine out of the box.

The scene importer has been changed to generate `.unwrap_cache` files
next to the imported scene files. These files *SHOULD* be added to any
version control system as they guarantee there won't be differences when
re-importing the scene from other OSes or engine versions.

This work started as a Google Summer of Code project; Was later funded by IMVU for a good amount of progress;
Was then finished and polished by me on my free time.

Update copyright statements to 2021
Happy new year to the wonderful Godot community!

2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.

We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)

Here's to a great year 2021 for all Godot users 🎆

15e57a0235 Remove buffer orphaning options project settings
These were only put in for the betas, in order to test hypotheses for stalling on Macs. It seems that most of the problems in the Mac editor have been solved by fixing the excessive redraw_requests.

As a result no one has reported any results from these options, but in future we will be able to refer users to try the beta versions, so there is no need to include them in the stable release. Indeed they are only likely to cause confusion.

Fix PanoramaSky artifacts on Android/GLES2

8825aa8b5b Fixes #43667.
The root cause of the issue is that OpenGL ES 2 does not support the `textureCubeLod` function.
There are (optional) extensions to support this, but they don't appear to be exposed with the ES2 renderer (even though the hardware needed to support LOD features are certainly available.)
The existing shim in `drivers/gles2/shaders/cubemap_filter.glsl` just creates a macro:

```
 #define textureCubeLod(img, coord, lod) textureCube(img, coord)
```

But the third parameter of `textureCube` is actually a mip bias, not an absolute mip level.
(And it doesn't seem to work regardless.)
In this specific case, the `cubemap_filter` should only sample from the first level of the "source" panorama cubemap.
In lieu of a method to force a lod level of zero, I've chosen to comment out the switchover from a 2D equirectangular panorama to the cubemap version of the same image, therefore always sampling roughness values from the 2D equirectangular panorama.
This may cause additional artifacts or issues across the seam, but at least it prevents the glaringly obvious black areas.

---

This same issue (no fragment texture LOD support) has rather large repercussions elsewhere too; it means materials with larger cubemap density (i.e. planar or distant objects) will be far rougher than expected.
Since GLES 3 appears to properly support fragment `texture*Lod` functions, switching to the GLES 3 backend would solve this problem.

---

Root cause discovered with help from @KaadmY.

8f6a6ac8d0 Add interpolation parameter to resize_to_po2()
Image::resize_to_po2() now takes an optional p_interpolation parameter
that it passes directly to resize() with default value INTERPOLATE_BILINEAR.

GLES2: call resize_to_po2() with interpolate argument

Call resize_to_po2() in GLES2 rasterizer storage with either
INTERPOLATE_BILINEAR or INTERPOLATE_NEAREST depending on TEXTURE_FLAG_FILTER.

This avoids filtering issues with non power of two pixel art textures.

7c4cf1c043 Batching - BackBuffer copy fix
For fixing a previous issue state.canvas_texscreen_used was reset to false at the start of each render_joined_item. This was causing a later shader that used SCREEN_TEXTURE to force recapturing the back buffer immediately prior to use, which we don't want.

This PR preserves the state across joined items, and also prevents joining of items that copy the back buffer as this may be problematic.

It turns out that the original issue that needed the line is now fixed, and the later issue is also fixed by removing it.

3c69377f10 2d Legacy - close vulnerabilities and more debug checks
While adding more debug checks to legacy renderer, I closed 2 types of vulnerabilities:

* TYPE_PRIMITIVE would previously read from uninitialized data if only specifying a single color
* Other legacy draw operations would fail in debug AFTER accessing out of bounds memory rather than before

debda7f411 Reverting changes to legacy polys and generic prims
Due to my less than eagle-like view over these functions I had assumed they were passing in a single buffer input for the changes to make buffer uploading more efficient. They aren't, which is less than ideal.

So these particular changes should be reverted. When I have some more time I'll see whether the API for these calls can be changed, because as is the multiple glSubBufferData calls could be causing stalls on some hardware.

ecd39094ed GLES2 2D fix normal mapping - batching and nvidia workaround
Normal mapping previously took no account of rotation or flips in any path except the TEXTURE_RECT (uniform draw) method. This passed flips to the shader in uniforms.

In order to pass flips and rotations to the shader in batching and nvidia workaround, a per vertex attribute is required rather than a uniform. This introduces LIGHT_ANGLE which encodes both the rotation of a quad (vertex) and the horizontal and vertical flip.

In order to optionally store light angles in batching, we switch to using a 'unit' sized array which can be reused for different FVF types, as there is no need for a separate array for each FVF, as it is a waste of memory.

The command syncronization would incorrectly start from first transform, instead of the current transform in these circumstances, which could have the result of missing drawing some commands from the end of the batch.

This had been shown in the wild occuring in debug collision polys. It was a benign error (sometimes visual elements would be lost), but did not cause any serious problems.

For textures that were imported as wrapping, the legacy renderer relied on GL repeat state being set as a once off during load, and didn't alter the GL wrapping state at runtime.

Batching was setting wrapping according to the CANVAS_RECT_TILE flag on rects, however this reset GL wrapping to clamp after use, which was conflicting with later drawcalls that relied on the default wrapping being preserved.

In this PR we only set the wrapping in GL if the texture has not been imported with wrapping. This duplicates the logic in the legacy renderer and solves the state bug.

a4bd66f854 GLES2 Batching - prevent baking on VERTEX use in a shader
Using the operator += in a shader is classified as an 'assign', and so is classified as a write rather than a read. This means that we need to prevent vertex baking on either a write or read (i.e. on usage), rather than just on reads.

94d127ccc3 GLES2 Batching - Fix try_join_item logic for lights
The old logic was incorrect, the first item with lights would prevent joining the next item in case it didn't have lights. Now the check is deferred so that items without lights check to see if the previous item had lights, and if so they prevent a join.

7bf9787921 SCons: Format buildsystem files with psf/black
Configured for a max line length of 120 characters.

psf/black is very opinionated and purposely doesn't leave much room for
configuration. The output is mostly OK so that should be fine for us,
but some things worth noting:

- Manually wrapped strings will be reflowed, so by using a line length
  of 120 for the sake of preserving readability for our long command
  calls, it also means that some manually wrapped strings are back on
  the same line and should be manually merged again.

- Code generators using string concatenation extensively look awful,
  since black puts each operand on a single line. We need to refactor
  these generators to use more pythonic string formatting, for which
  many options are available (`%`, `format` or f-strings).

- CI checks and a pre-commit hook will be added to ensure that future
  buildsystem changes are well-formatted.

Writing to COLOR in a custom shader can result in incorrect results if colors are baked (vertex color and modulate). This PR prevents baking with COLOR output, except under the special circumstances that final modulate is (1, 1, 1, 1), in which case the result will be correct.

Use DWMEnableBlurBehindWindow instead of WS_EX_LAYERED
Affects per-pixel transparency

The current method renders to the screen by copying the GLES output to a
DIB for transparency using the CPU instead of rendering directly to the
window via the GPU. This is slower and also forces the window to be borderless
as WS_EX_LAYERED affects the non-client region as well.

This change uses DWMEnableBlurBehindWindow which allows using the standard
glClearColor() background alpha and is also performed through the GPU,
eliminating CPU bottlenecks

Adding the ability to access MODULATE in the shader breaks when final_modulate is baked into vertex colors (this is a technique used to batch together different colored items). This PR prevents baking vertex colors when MODULATE is detected in the shader.

It also prevents baking when COLOR is read in canvas shaders, which could currently produce the wrong result in the shader if colors were baked. It does not prevent baking if COLOR is only written, which happens in most shaders, and will operate correctly without baking.

451c3fc0fb GLES2 2D batching - item reordering, light joining and light modulate fix
Although 2D draws in painters order with strict ordering, in certain circumstances items can be reordered to increase batching / decrease state changes, without affecting the end result. This can be determined by an overlap test.

In situation with item:
A-B-A
providing the third item does not overlap the second, they can be reordered:
A-A-B

Items already contain an AABB which can be used for this overlap test.

1)
To utilise this, I have implemented item reordering (only for single rects for now), with the lookahead adjustable in project settings. This can increase performance in situations where items may not be grouped in the scene tree by texture. It can also be switched off (by setting lookahead to 0).

2)
This same trick can be used to help join items that are lit. Lit items previously would prevent joining completely, thus missing out on performance gains other than multi-command items such as tilemaps.

In this PR, lights are assigned as bits in a bitfield (up to 64, the optimization is disabled above this), and on each try_item (for joining), the bitfield for lights and shadows is constructed and compared with the previous items. If these match the 2 items can potentially be joined. However, this can only be done without changing the rendered result if an overlap test is successful.

This overlap test can be adjusted to join items up to a specific number of item references, selectable in project settings, or turned off.

3)
The legacy uniform single rect drawing routine seems to have been identified as the source of flicker, particularly on nvidia. However, it can also be up to 2x as fast. Because of the speed the batching contains a fallback where it can use the legacy single rect method, but I have now added a project setting to make this switchable. In most cases with batching it should not be necessary (as single rects are drawn less frequently) and thus the flickering can be totally avoided.

4)
This PR also fixes a color modulate bug when drawing light passes, in certain situations (particularly custom _draw routines with multiple rects).

5)
This PR also fixes #38291, a bug in the legacy renderer where light passes could draw rects in wrong position.

Polygon2D:
The property wasn't used anymore after switching from canvas_item_add_polygon() to canvas_item_add_triangle_array() for drawing.

Line2D:
Added the same property as for Polygon2D & fixed smooth line drawing to use indices correctly.

5ab3b61520 Restructure depth_internalformat code to work on mobile
This changes the code path so that `glRenderBufferStorage*` always uses
values appropriate for renderbuffers and `glTexImage2D` never uses an
internalformat meant for buffers.

Fixes #33825.

bb1d75f55e glTexImage2D: Fix confusion between format and internal format
The `format` parameter is similar to `internalFormat` but takes different
values, and especially only `GL_DEPTH_COMPONENT` for depth, without size
specifier.

Cf. https://www.khronos.org/registry/OpenGL-Refpages/es3.0/html/glTexImage2D.xhtml

Fixes a regression from #33278 and another occurrence.

47389c3a16 Partial revert of #32657, undoing line shifting by 0.5
As discussed in #32657, this can't be done here as lines can be used
with a canvas scale, and this breaks them.
A suggestion is to do the pixel shifting at matrix level instead.

Fixes #33393.
Fixes #33421.

418b035dda fix #33188 MSAA depth buffer not used for external texture
When rendering to an external texture and MSAA was active (as happened
in the Oculus Mobile ARVR plugin) no MSAA was rendered as the correct
depth buffer and multisample texture target was not used.
This also fixes https://github.com/GodotVR/godot_oculus_mobile/issues/54

69003457b3 WebGL 2.0: Force decompressing non power-of-2 textures with repeat/mipmap
While OpenGL ES 3.0 and WebGL 2.0 both support non power-of-2 (NPOT)
textures in their specification, the situation seems to be less clear
about *compressed* NPOT textures using repeat or mipmap flags.

At least Chrome on Linux doesn't seem to support this combination,
and a variety of mobile hardware have similar limitations.

As a workaround, we force decompressing such textures when running on
WebGL 2.0, at the cost of loading time and memory usage.

Fixes #33058.

bdaedb601c Fix draw_rect
OpenGL uses the diamond exit rule to rasterize lines. If we don't shift
the points down and to the right by 0.5, the line can sometimes miss a
pixel when it shouldn't. The final fragment of a line isn't drawn. By
drawing the lines clockwise, we can avoid a missing pixel in the rectangle.
See section 3.4.1 in the OpenGL 1.5 specification.
