Immediate meshes do not have geometry of type Surface so we check
to see the mesh isn't immediate before trying to cast to surface
to check for octahedral compression
This patch fixes rendering of multiple reflection probes for a single
mesh in the GLES2 renderer. If there were two reflection probes, one of
them would always have the `interior` option flipped, resulting in
broken blending between probes and flickering of ambient reflection.
Also make note of GLES2 reflection probe limit
This provides more realistic lighting with a very small performance cost.
The option is available in both GLES3 and GLES2, and can be enabled in
the Project Settings. This goes well with the ACES Fitted tonemapping mode
that was recently added.
When enabled, this also makes upgrading Godot 3.x projects to Godot 4.0 easier,
since lighting in 3.x will better match how it'll look in Godot 4.0.
Change the existing DEV_ASSERT function to be switched on and off by the DEV_ENABLED define. DEV_ASSERT breaks into the debugger as soon as hit.
Add error macros DEV_CHECK and DEV_CHECK_ONCE to add an alternative check that ERR_PRINT when a condition fails, again only enabled in DEV_ENABLED builds.
Update mesh_surface_get_format_stride and
mesh_surface_make_offsets_from_format to return an array of offsets and
an array of strides in order to support vertex stream splitting
Update _get_array_from_surface to also support vertex stream splitting
Add a condition on split stream usage to ensure it does not get used on
dynamic meshes
Handle case when Tangent is compressed but Normal is not compressed
Make stream splitting option require a restart in the settings
Update SoftBody and Sprite3D to support and use strides and offsets
returned by updated visual_server functions
Update Sprite3D to use the dynamic mesh flag
This restores Windows platform file handling back to open files non-exlusively by default, as was the case before October 2018. (See b902a2f2a7)
Back then, while fixing warnings for MSVC, the function used for opening files was changed from _wfopen() to _wfopen_s() as suggsted by the warning C4996. ("This function may be unsafe, consider using _wfopen_s instead.")
This new function
1. did parameter validation and thus avoided some possible security issues due to nil pointers or wrongly terminated strings
2. it also changed the default file sharing for opened files from _SH_DENYNO (which was the implicit default for the previous _wfopen()) to _SH_SECURE.
_SH_DENYNO means every opened file could be opened by other calls (like is the default on other operating systems).
_SH_SECURE means if the file is opened with READ access, others can still read the same file, but if it is opened with WRITE access, others can't open it at all, not even to read.
This led to rarely occuring bugs on Windows, i.e. due to random access by Antivirus processes, or Godot/Windows not closing a file handle fast enough while trying to open it again elsewhere (i.e. project.godot, instead showing the Project manager, or saving shaders/debugging the game).
What this PR does it change the file access to a third method, _wfsopen(). This is still secure, doing parameter validation and thus avoids the warning, but it allows us to actually SET the file sharing parameter. And we set it to _SH_DENYNO, as it was implicitely before the change. (And as it currently is on all non-Windows platforms, where file sharing restrictions don't exist by default.)
Warning C4996 should really have been pointing this out. It should've been _wfsopen() all along. Let's hope this banishes those annoying, rare errors for all eternity.
Fixes#28036.

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.
