AnimBrush

AnimBrush is an animated bitmap file format used on Amiga computers. It is a variant or subformat of ANIM format. It is associated with the AnimBrush feature of Deluxe Paint III and IV.

The format was also commonly used by the ToolManager application (at least ToolManager v2.x).

 * ANIM-5 XOR mode
 * Non-interleaved (interleave=1)
 * Initial frame is uncompressed (instead of PackBits)
 * Transparency
