+ * 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
