This removes "buggy driver paranoia", which set sizeimage equal to
at least width * height * 2. This was a false assumption when the
pixel format only required 1 byte per pixel. Originally, the
paranoia was in place to handle drivers which incorrectly set
sizeimage=0, but these seem to have been fixed.
