where PROPERTY_USAGE_GROUP is.

DocData: Skip unexposed classes

Revert "Made possible to specify where to dump the contents when load…

Properly expose classes that we actually want accessible.

Add missing enum bindings.

Update many docs with recent rendering changes

Update TextEdit docs - explaining 'override_selected_font_color' role

This reverts commit 3c261e0d.

This was not so useful as is due to the way dependency paths are stored
in scenes and resources.

Correct Dictionary addition of a key and the duplication of a variable name.

Ability to create local RenderingDevice instances.

Document DynamicFont limitations and a possible workaround

SCons: Disable -Werror on 'stable' releases

Implement global and per instance shader uniforms.

Add light size to Sky Shaders

Document image size limits

Clarify that angles must be specified as radians in the documentation

Activate Physics Process in SpringArm3D.

Adds two keywords to shader language for uniforms:
-'global'
-'instance'

This allows them to reference values outside the material.

This closes #30014.

This closes #30238.

Use sky properly for ambient and reflections

Stable releases are tagged and need to stay easy to compile in the future.
As new compiler versions introduce new warnings or catch more occurrences,
have -Werror set in tagged releases could be a bother.

We still want it on by default for all Godot developers, so it's now
conditional.

This closes #36356.
