// color has the same format as the texture, it only works when the
// texture has an alpha channel. So the driver falls back to software
// when the repeat mode is RepeatNone, the picture has a non-identity
// transformation matrix, and doesn't have an alpha channel.
// Since we only scale the picture, we can work around this by setting
// the repeat mode to RepeatPad.
