Notes:
- Tossed old code now that FXCursor has an RGBA representation.
- Now uses actual alpha color from the GIF file.
- Need function to force alpha channel based on transparent color.
- Optionally let system guess a transparancy color based on the corners.
- If that doesn't work, you can force a specific transparency color.
