211dc8cd2d BVH - add option for expanded AABBs in leaves
This PR adds a define BVH_EXPAND_LEAF_AABBS which is set, which stores expanded AABBs in the tree instead of exact AABBs.

This makes the logic less error prone when considering reciprocal collisions in the pairing, as all collision detect is now taking place between expanded AABB against expanded AABB, rather than expanded AABB against exact AABB.

The flip side of this is that the intersection tests will now be less exact when expanded margins are set.

All margins are now user customizable via project settings, and take account of collision pairing density to adjust the margin dynamically.

cc8846bef6 Added material_overlay property to MeshInstance
Applying overlay materials into multi-surface meshes currently
requires adding a next pass material to all the surfaces, which
might be cumbersome when the material is to be applied to a range
of different geometries. This also makes it not trivial to use
AnimationPlayer to control the material in case of visual effects.
The material_override property is not an option as it works
replacing the active material for the surfaces, not adding a new pass.

This commit adds the material_overlay property to GeometryInstance
(and therefore MeshInstance), having the same reach as
material_override (that is, all surfaces) but adding a new material
pass on top of the active materials, instead of replacing them.

Implemented in rasterizer of both GLES2 and GLES3.

788f075b44 Portals - Allow user to set roaming expansion margin
Previously a crude metric was used to decide on the roaming expansion margin, but it created unexpected results in some scenarios. Instead this setting is exposed to the user via the RoomManager, allowing them to tailor it to the world size, room sizes, roaming objects sizes and the speeds of movement.

4c710780d4 Implement async shader compilation plus caching for GL ES 3
Async. compilation via ubershader is currently available in the scene and particles shaders only.

Bonus:
- Use `#if defined()` syntax for not true conditionals, so they don't unnecessarily take a bit in the version flagset.
- Remove unused `ENABLE_CLIP_ALPHA` from scene shader.
- Remove unused `PARTICLES_COPY` from the particles shader.
- Remove unused uniform related code.
- Shader language/compiler: use ordered hash maps for deterministic code generation (needed for caching).

ab76cd6ff2 Faster editor line drawing - Path2D and draw_line
Changes the Path2D drawing to use POLYLINE instead of thick lines.
Add a path to translate thick lines (that are not using anti-aliasing) to draw as polygons instead. This should be faster because polygons can be batched.

clang-format: Disable alignment of operands, too unreliable
Sets `AlignOperands` to `DontAlign`.

`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.

d878fe7b90 Sphere occluders - self occlusion and improvements
Sphere occluders are now tested for self occlusion. Spheres that are behind another sphere in the current view are superfluous so can be removed, cutting down on the runtime calculations.

AABBs are now maintained for Occluders as well as individual spheres, meaning a bunch of occluder spheres can be frustum rejected as a block.

Add a Viewport property to use full floating-point precision in HDR
This is only available on the GLES3 backend.

This can be useful for advanced shaders, but it should generally
not be enabled otherwise as full precision has a performance cost.
For general-purpose rendering, the built-in debanding filter should

546e207d8f Portals - Fix cull roaming through multiple portals
Small bug in the logic, the roaming objects only should be set to done when they have been marked as visible, rather than the first time they are examined. This is because they can be seen in a room through multiple portals, and each needs to be tested until there is either a visible result or all the portals in are visited.

Add high quality glow mode
This backports the high quality glow mode from the `master` branch.

Previously, during downsample, every second row was ignored.
Now, when high-quality is used, we sample two rows at once to ensure
that no pixel is missed. It is slower, but looks much better and has
a much high stability while moving.

High quality also takes an additional horizontal sample the width of the
horizontal blur matches the height of the vertical blur.

Temporarily revert to the simple PVS generation method, because I've noticed a bug in the complex version, and the simple version is safer while I fix this.

69cc759b65 Portals - improve PVS tracing
The existing tracing routine for building the PVS was rather simple compared to the main portal tracing, and could not correctly cope with paths that went through multiple portals from room A to B, and as a result would sometimes miss room entries in the PVS resulting in too many culled rooms in these circumstances.

This PR adds an improved function that can cope with entering a room multiple times during a trace. As a result it has to take care of portal directions (to prevent going back on itself) in a similar, but not identical way to the main portal tracing routine, and internal rooms, to prevent recursive loops.

2c88517a7b Portals - fix recursive loop looking out from internal rooms
In some situations looking out from an internal room it was possible to look back into the portal into the internal room.

This PR fixes this by keeping a single item 'stack' record of the last external room, and preventing recursing into this room. This also makes tracing significantly more efficient out of internal rooms, as there is no need to trace the external room multiple times.

776623d56b Portals - Improve UI and add shortcuts
This PR makes the 'convert rooms' button permanently on the toolbar and accessible whichever node is selected, so you can convert rooms without having to select the RoomManager first.

It also adds a togglable item 'view portal culling' to the 'View' menu which is a simple way of setting the RoomManager 'active' setting without the RoomManager being the selected node.

Both of these have keyboard shortcuts, which should make it much faster to reconvert rooms and edit.

In addition there the string in the 'Perspective' Listbox is modified to show [portals active] when portal culling is operational, for visual feedback. This is updated when you change modes, and when the rooms are invalidated.

93c78af488 Portals - disable frustum culling gizmos with preview camera
When using the preview camera feature it turns out as well as culling the game objects, this also culls the editor gizmos from the preview camera, which makes the editor hard to use in this mode.

To get around this problem we simply disable frustum culling for GLOBAL portal_mode objects when in preview camera mode. This could be a bit slower in an editor scene with lots of gizmos but is the simplest way of solving the problem.

44f9a0f961 Portals - fix autolink sprawling, refine logs
It turned out the new autolinking feature was linking portals AFTER the static meshes had been added to rooms in the PortalRenderer. This meant that large meshes weren't being sprawled across these portals. The fix involves doing the autolinking BEFORE adding the static meshes.

Fixes a bug in the warning for portals being in the wrong direction, they should have only been checkout for outgoing portals. This was resulting in erroneous warnings.

Also the room conversion logs are refined to be more compact and informative.

A warning icon is also added in the gizmo for portals where autolink fails.

Add support for contrast-adaptive sharpening in 3D (GLES3 only)
This is an older, easier to implement variant of CAS as a pure
fragment shader. It doesn't support upscaling, but we won't make
use of it (at least for now).

The sharpening intensity can be adjusted on a per-Viewport basis.
For the root viewport, it can be adjusted in the Project Settings.

Since `textureLodOffset()` isn't available in GLES2, there is no
way to support contrast-adaptive sharpening in GLES2.

It turns out the calculation of the bounding rect for canvas items has a nasty bug.

- 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.

62f344f448 Properly disable dynamic lights on baked instances.
Automatically set the `baked_light` bool when applying a lightmap to an
instance. This ensures the disabling of dynamic lights when the
bake mode is set to ALL.

847a37b196 Change 2d transform snapping from floor to round
Two common problems have emerged as a result of transform snapping:
1) Camera jitter with a camera following a snapped object
2) Pixel gaps between e.g. a platform and a player, where a platform rounds down and a player rounds up

Using round seems to greatly reduce problems due to camera jitter. It also may prove better for  pixel gaps because pixel art is often designed on a grid, so whole numbers are too expected, which are unstable with floor().

4485b43a57 Modernize atomics
- Based on C++11's `atomic`
- Reworked `SafeRefCount` (based on the rewrite by @hpvb)
- Replaced free atomic functions by the new `SafeNumeric<T>`
- Replaced wrong cases of `volatile` by the new `SafeFlag`
- Platform-specific implementations no longer needed

6d89f675b1 Modernize Thread
- Based on C++11's `thread` and `thread_local`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed (except for the few cases of non-portable functions)
- Simpler for `NO_THREADS`
- Thread ids are now the same across platforms (main is 1; others follow)

4ddcdc031b Modernize Mutex
- Based on C++11's `mutex`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed
- Simpler for `NO_THREADS`
- `BinaryMutex` added for special cases as the non-recursive version
- `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`.
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.

a814dda2ae BVH - fix deferred visible mesh collision check
When making items visible from the visual server, the collision check is deferred to prevent two identical collision checks when set_pairable is called shortly after.

It turns out that for some items (especially meshes), set_pairable is never called. This PR detects this occurrence and forces a collision check at the end of the routine.

00bd087d82 BVH add support for visibility (activation)
A major feature lacking in the octree was proper support for setting visibility / activation. This meant that invisible objects were still causing lots of processing in the tree unnecessarily.

This PR adds proper support for activation, items are temporarily removed from the tree and collision detection when inactive.
