* The DIU only supports cursors up to 32x32 (MAX_CURS). We reject cursors
* larger than this, so we already know that 'width' <= 32. Therefore, we can
* simplify our code by using a 32-bit big-endian integer ("line") to read in
* a single line of pixels, and only look at the top 'width' bits of that
* integer.
*
* This could result in an unaligned 32-bit read. For example, if the cursor
* is 24x24, then the first three bytes of 'image' contain the pixel data for
* the top line of the cursor. We do a 32-bit read of 'image', but we look
* only at the top 24 bits. Then we increment 'image' by 3 bytes. The next
* read is unaligned. The only problem is that we might read past the end of
* 'image' by 1-3 bytes, but that should not cause any problems.
