Fix #36134

Fix docs generation for Vector2i/Vector3i/Rect2i

Vulkan: Initialize struct members on declaration

SCons: Validate dependencies for linked multimedia modules

Supersedes and closes #38945.

Add color option for img bbcode tag in RichTextLabel to tint images

Disable antialiasing on the DynamicFont outline as well when requested

Grabbing focus on ProjectList after clicking an item.

Print errors when calling MIDI input methods on unsupported platforms

Prevent crash attaching a script with no languages registered

Move `RayShape2D` implementation into its own translation unit

This is still a bit hacky and eventually we should rework the way we handle
optional dependencies (especially with regard to builtin/system libs), but
it's a simple first step.

Fixes #39219.

Add performance hints to the DirectionalLight shadow mode property hint

Improved warning shown when autoload cannot be added.

Clarify usage of AnimationPlayer with AnimationTree and fill empty doc descriptions

When using the default setting (layer 1 set only) nothing is stored in the tscn file for a Light2D, hence it relies on the value in the constructor.

The problem is the constructed value is 1 in Light2D, and -1 in RasterizerCanvas::Light. -1 results in all bits being set so all occluders are shown, rather than just those in layer 1.

This PR changes Rasterizer::Canvas constructor to set to 1. An alternative is to have -1 as the value for layer 1 throughout.

Fix inconsistent error messages with Android custom export templates

Add clarification to docs to explain that when an `AnimationPlayer`
object is paired with an `AnimationTree`, several properties and
methods exposed by the `AnimationPlayer` class may not work as expected.
The issues occur because an `AnimationTree` runs independently, and
uses its member `AnimationPlayer* player` primarily for its
`Map<StringName, AnimationData> animation_set`.

Added descriptions for `root_motion_track` and `get_root_motion_transform`.

 Update OSX joypad GUID to SDL uid conversion.

This also clarifies some parts in the DirectionalLight documentation.
