And finally remove the 'frames' property which was added for compatibility with 2.1
in bed3efb17e.
Fixes#21765.
The 'animations' property on the other hand is needed, contrarily to what its comment
said (copy-paste mistake probably).
Also removes unused '_get_animation_list'.
This makes it easier to spot syntax errors when editing the
class reference. The schema is referenced locally so validation
can still work offline.
Each class XML's schema conformance is also checked on GitHub Actions.
Both AnimatedSprite2D and AnimatedSprite3D use a SpriteFrames resource, but the SpriteFrames
class description currently only lists being used with the 2D variant.
For the time being we don't support writing a description for those, preferring
having all details in the method's description.
Using self-closing tags saves half the lines, and prevents contributors from
thinking that they should write the argument or return documentation there.
Lots of internal API changes and some docstrings were lost in the conversion.
I manually salvaged many of them but for all the rendering-related ones, an
additional pass is needed.
Added missing enum bindings in BaseMaterial3D and VisualServer.
We already removed it from the online docs with #35132.
Currently it can only be "Built-In Types" (Variant types) or "Core"
(everything else), which is of limited use.
We might also want to consider dropping it from `ClassDB` altogether
in Godot 4.0.
Rename user facing methods and variables as well as the corresponding
C++ methods according to the folloming changes:
* pos -> position
* rot -> rotation
* loc -> location
C++ variables are left as is.
