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.
- Enable 4× MSAA in all 3D demos.
- Enable filmic tonemapping with a whitepoint of 6 in GLES3 3D demos.
- Add subtle fog to the Truck Town demo.
- Use the `2d` stretch mode and `expand` stretch aspect to support
multiple resolutions and aspect ratios.
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.
Importing ETC2 textures is slow and requires a lot of RAM, so it
makes sense to disable it. Those who would like to run the demo
on mobile platforms can re-enable it in the Project Settings.
Noticed a lot of error spat out because of unnormalized basis.
I simply followed the suggestion to use get_rotation_quat() instead of using constructor of Quat(x).
