* NOTES:

- * The code for depths like 24 that don't have integer number of pixels per
- * long is broken and needs to be fixed. For now I turned these types of
- * mode off.
- *
* Also need to add code to deal with cards endians that are different than
* the native cpu endians. I also need to deal with MSB position in the word.
