Edited the project settings to match the new Godot 4 standard and fixed
the script errors which were making it impossible to run this demo.
Now everything works properly for the 4.0-dev version.
Changed to Vulkan Mobile + Changed argument name
Followed the suggestions of aaronfranke
Changed viewport size
This is required to benefit from crisp display on hiDPI monitors.
This also fixes issues related to fullscreen and input handling
when using an hiDPI display on Windows.
This makes demos render correctly on hiDPI displays,
while also demonstrating how to handle multiple resolutions.
The 3D in 2D demo now uses "3D No-Effects" for the 3D viewport,
which is faster to render. Thanks to this, 4× MSAA is now enabled
for a better result.
The background loading demo now uses mipmaps for better-looking images.
The material testers demo now samples mouse input in a
resolution-independent manner when panning.
Default clear colors were also changed in some projects for visual
consistency with the project's theme.
