    Message : Convert DXT1 RGB data to DXT3 RGBA when uploading to the GPU. DXT1 has a specific 'BLACK' code that results in transparent black pixels when sampled. D3D does not have specific RGB-only DXT1 formats like OpenGL does so when this code is encountered, we sample 0 alpha for these pixels when GL would expect 1 because the alpha channel should not exist. Work around this by converting to DXT3 RGBA, adding an extra block of 1.0 alpha pixels for each color block. Mac Intel OpenGL requires additional workarounds to always sample 1.0 alpha. Set the texture swizzle parameters to force it.
