- Move all demo projects that don't require Forward+/Mobile-only features
to the Compatibility rendering method. This improves performance significantly
on low-end devices and ensures visuals are identical to a web export
of the demo.
- Set deadzone on all inputs to 0.2 for better gamepad usability.
- Remove reliance on `default_env.tres` to use built-in Environment
resources in the main scene instead (which follows the preview environment
workflow).
- Remove notices pointing to GDNative or VisualScript, since both were
removed in 4.0.
- Various bug fixes and usability tweaks to 10+ demos.
* Remove unnecessary use of `self`
* Connect to signals directly over `connect("name")`
* Use `call_deferred` on callables over `call_deferred("name"))`
* Emit signals directly over `emit_signal("name"...)`
All demos were opened with Godot 4.2.1, with the mesh format
upgraded for 3D demos.
The 3D antialiasing demo now uses Extra Cull Margin on the last
object to prevent it from disappearing too early when the camera
rotates (due to its use of shader-based animation).
