Texture formats
Texture decoding / sampling
The textures are sampled by the texture shader portion of NV2A/Pixel_Combiner.
Texture signedness
Each component of the texture can be either signed (two's-complement) or unsigned.[1][FIXME].
Texture filtering
The GPU implements the standard texture filters as known from OpenGL. In addition, it supports convolution filters[2][FIXME].
