if present. - Modified GZDoom's true color texture copy functions and added them to generate 32 bit D3D textures. Paletted TGAs and PCXs are also handled this way but I don't think these 2 formats are worth some more special handling. (Question: Is it worth it to implement special handling for paletted PNGs so that they are used as 8 bit textures internally?) SVN r608 (trunk)
