- Did some restructuring of FMultiPatchTexture::CopyTrueColorPixels() so that it composites to

Browse source 
a temporary bitmap before copying to the destination bitmap if any fancy stuff is going on.
  This simplifies the part drawing, since it doesn't need to check if each part is a multipatch
  texture. It also means it can reliably use copy operations other than OP_COPY.
