If the state tracker chooses to implement one format with a more general one (e.g. GL_ALPHA implemented with GL_RGBA) we end up in a situation where some components should be ignored. Readpix handles this correctly, but blit does not, which means that if we blit between different formats we can end up writing garbage into some components. Work around this by adding an explicit swizzle to the pipe_blit_info struct, which can re-arrange elements and/or put 0 or 1 into appropriate channels, and use this to set the appropriate values into unused channels via the sampler view.
