A background graphics compressor/decompressor for SCUMM v2, v5 and v6 resources.

For V5/6, it only compresses losslessly and without transparency. Normally, it leaves lots of room for the basic EGA palette and any colours used by sprites (an advanced system would reconcile all sprites used in a room and their colours with the background's palette), so backgrounds are limited to 160 colours by default, but this can be configured. Images must be PNG, and requires game resources contained within an "LFLF" directory as dumped/accepted by ScummPacker.

For V2, it works on resources output from scummrp.

There is also experimental support for V1 resources, including object images, as output by scummrp; however, it does not look like scummrp can insert the generated resources back into the original games files. I'm not sure why. Note that scummrp also does not output the common colour palette; you can use the included v1col_extract and v1col_insert tools to get this information.

Full instructions are available in the Readme.txt file included.
