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.
This is part of effort to make more efficient use of the API for devices with poor drivers. This eliminates multiple calls to glBufferSubData per update.
Batching is mostly separated into a common template which can be used with multiple backends (GLES2 and GLES3 here). Only necessary specifics are in the backend files.
Batching is extended to cover more primitives.
Don't apply lighting to objects when they have a lightmap texture and
the light is set to BAKE_ALL. This prevents applying the same direct
light twice on the same object and makes setting up scenes with mixed
lighting much easier.
Option in MeshInstance to enable software skinning, in order to test
against the current USE_SKELETON_SOFTWARE path which causes problems
with bad performance.

Fixes: #28683, #28621, #28596 and maybe others
For iOS we enable pvrtc feature by default for both GLES2/GLES3
Etc1 for iOS doesn't have any sense, so it disabled.
Fixed checks in export editor.
Fixed pvrtc ability detection in GLES2 driver.
Fixed pvrtc encoding procedure.
Add __NetBSD__ to `platform_config.h` so that it can find `alloca`
and use the proper `pthread_setname_np` format.
Rename RANDOM_MAX to avoid conflict with NetBSD stdlib.
Fixes#42145.
(cherry picked from commit 5f4d64f4f3)
- Fade reflection towards inner margin and clip it at screen edges instead of external margin.
- Round edges of the fade margin if both are being cut off to prevent sharp corners.
Previously VS::INSTANCE_NONE was returned for Lightmap data, this caused `visual_server_scene.cpp` to assert in `instance_set_use_lightmap()`
Now `dummy_rasterizer.h` returns `VS::INSTANCE_LIGHTMAP_CAPTURE` for lightmap capture data thus satisfying `visual_server_scene`
When not using TEXTURE_RECT path, flips have to sent via another method to the shader, to ensure that normal maps are correctly adjusted for direction. This PR adds an extra vertex attribute, LIGHT_ANGLE.
For nvidia workarounds, where the shader still has access to the final transform and extra matrix, the LIGHT_ANGLE can be 0 (no adjustment), 180 degrees for a horizontal flip, and negative indicates a vertical flip.
For batching path, the LIGHT_ANGLE can be used to directly specify the light angle for normal mapping, even when the final transform and extra matrix have been baked into vertex positions, so the same shader can be used for both.
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.
In rare circumstances an item would issue multiple transform commands before a (non rect) draw command. 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.
This PR fixes this synchronization error.
Compiler is usually in the best position to decide whether to inline functions. Great care must be taken using FORCE_INLINE because it can have unforeseen consequences with recursion, loops and bloat to the executable.
Here some FORCE_INLINES are removed in order to allow the compiler to make best choice and remove a compilation warning where unable to inline during a recursive function.
Fixes#41226
On platforms that don't report support for GL_REPEAT for non power of two textures, the FORCE_REPEAT conditional is used instead. However for rect batches, the conditional was being set AFTER binding the shader, which meant it wasn't being activated.
This PR simply shifts setting the conditional to before the shader bind.
1. Removed errors in mesh_surface_get_array as it's supported now
2. More accurate errors in mesh_surface_get_blend_shapes
