This is exactly how Windows-icons/cursors work. In fact under Windows icons 
and cursors share the same file-format, just one header field specifies what 
it is and only cursors specify a hot spot.
The file consists of an XOR and an AND bitmap, the 1-bpp AND bitmap contains 
the mask and the 1,2,4,8,16 or 24-bpp XOR bitmap the actual image. Pixels 
that have a zero bit in the mask and a zero value in the image are 
transparent. A zero in the mask and all-ones in the image make a pixel the 
inverted background. 1-bits in the mask make the pixel have the colour from 
the image regardless of the background.
