Texture_format

Description
Exercises rendering a textured quad using various NV2A hardware texture formats. A color gradient is generated and converted to the target format (applying swizzling if swizzled), then sampled via the projective 2D shader stage with the final combiner set to output the sampled texture color. Also tests 8-bit palettized textures across various palette sizes and verifies alpha channel behavior for formats containing dummy "X" alpha components.
