* RESTRICTIONS
* Currently, only compression type 5 (Byte Vertical Delta Mode) is

* loading them with DPaint III and saving them again.
-* Sculpt-Animate pictures do not work, because I have no documentation

+* added soon.
* I will implement some more compression types upon request.

-* WARNINGS

* This routine needs at least 820 bytes of stack.
* The size of the bitmap is not checked by this routine, the planes
* must have at least the size described in the BMHD of the anim
* file.
