The built-in tiled-to-tiled copy packet doesn't support copying
between images that don't meet certain criteria such as alignment,
micro tile format, compression state etc.
To work around this, we copy the image piece by piece to a
temporary buffer that we know is supported,
and then copy it to the intended destination.
The implementation assumes that at least one pixel row of the
image fits into the temporary buffer, and will try to copy as
many rows as fit.
