Minor update to reflect an API change in v1.1 of the
Google Play Billing Library plugin.
The queryPurchases function changed to be asyncronous,
added a query_purchases_response callback to process
the results.
This change is dependent on the contents of:
https://github.com/godotengine/godot-google-play-billing/pull/25
- Enable anisotropic filtering in 3D demos, and set the quality to
16× on desktop and 4× on mobile.
- Enable 4× MSAA on some 3D demos that didn't use it beforehand.
- On GLES3 demos, disable MSAA on mobile as these demos are often
more demanding.
- Use more conservative framebuffer allocation settings for better
performance.
- Use PCF13 shadow filtering in GLES2 demos on desktop to benefit
from soft shadows in Godot 3.2.4 and later.
In Godot 3.2.3, this will make shadows smoother but still "blocky".
- Use Lossless compression instead of VRAM compression for
small textures such as the voxel demo texture atlas.
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.
