blendtable <blendtable> { [...] }
Loads a blend table from a raw image file.
The image file MUST contain a 256 color table of its own. Each pixel will have their matching color in the table converted in the blend table.
A single image file may contain multiple base palettes, and offset can used to locate it.
The first ID is reserved to the 33% transparency.
