File header:<br />
4 bytes - "ANIM"<br />
2 bytes - number of frames<br />
2 bytes - width<br />
2 bytes - height<br />
2 bytes - unknown<br />
<br />
Frame data starts with flags byte and 32-bit size.<br />
<br />
Flags meaning in the order they are checked:<br />
* 0x20 - explicit palette size present, read 32-bit value for it (otherwise use 768)<br />
* 0x01 - palette plus raw frame data<br />
* 0x10 - 8x8 tiled compression<br />
* 0x02 - masked update (first a bit mask for the whole frame is transmitted followed by updated pixel values)<br />
<br />
Tiled compression works by sending an opcode for each 8x8 tile:<br />
* 0 - fill tile with single colour<br />
* 1 - read two colours and 64-bit pattern telling which colour to use for each tile element<br />
* 2 - similar but with four colours and two bits per pixel in mask<br />
* 3 - eight colours and three bits<br />
* 4 - 16 colours/4 bits<br />
* 5 - leave tile unchanged<br />
* 6 - masked update: read 8-bit rows update mask, for the updated tile rows read 8-bit pixel update mask and pixel values for the updated positions<br />
* 7 - masked update but with simple 64-bit mask before updated pixels<br />
