Trilinear + NormalNx produces blurry camera textures

[Nash]

When using Trilinear filtering combined with NormalNx, it seems that the camera texture stays blurry like as if there's no NormalNx applied.

Camera textures cannot apply those upscalers as they are CPU-side and camera textures are strictly GPU-side.

While I agree that it isn't ideal visually, there's little there can be done here without porting over all the upscalers gzdoom has to GLSL shaders.

For camera textures I'd always advise to create them in higher resolution than map units - 4x at least.
Aside from that, nothing that can be done. Redoing the scalers in GLSL would be quite the performance killer on anything but high end hardware.

Yeah, creating a higher res canvas does reduce the "bug" somewhat. I'll accept that as a limitation.
