The 3D demos aren't very demanding and Godot has been optimized
a bit since 4.0's release, so we can afford using higher quality
shadow settings for less noisy shadow filtering.
This also tweaks shadow bias to reduce shadow acne in the Voxel demo.
The time slider in the Physical Light and Camera units demo now
allows for more precise adjustments.
This leads to code that is easier to understand and runs
faster thanks to GDScript's typed instructions.
The untyped declaration warning is now enabled on all projects
where type hints were added. All projects currently run without
any untyped declration warnings.
Dodge the Creeps and Squash the Creeps demos intentionally don't
use type hints to match the documentation, where type hints haven't
been adopted yet (given its beginner focus).
