Subject: Implement Zero-Configuration Resolution Scaling (#1365)
* Initial implementation of Render Target Scaling
Works with most games I have. No GUI option right now, it is hardcoded.
Missing handling for texelFetch operation.
* Realtime Configuration, refactoring.
* texelFetch scaling on fragment shader (WIP)
* Improve Shader-Side changes.
* Fix potential crash when no color/depth bound
* Workaround random uses of textures in compute.
This was blacklisting textures in a few games despite causing no bugs. Will eventually add full support so this doesn't break anything.
* Fix scales oscillating when changing between non-native scales.
* Scaled textures on compute, cleanup, lazier uniform update.
* Cleanup.
* Fix stupidity
* Address Thog Feedback.
* Cover most of GDK's feedback (two comments remain)
* Fix bad rename
* Move IsDepthStencil to FormatExtensions, add docs.
* Fix default config, square texture detection.
* Three final fixes:
- Nearest copy when texture is integer format.
- Texture2D -> Texture3D copy correctly blacklists the texture before trying an unscaled copy (caused driver error)
- Discount small textures.
* Remove scale threshold.
Not needed right now - we'll see if we run into problems.
* All CPU modification blacklists scale.
* Fix comment.
