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.

The following PNG image contains the blend table in Duke Nukem 3D v1.5:
This example will load 3 blend tables in the same file:
blendtable 0 { raw { file "blend.raw" } }
blendtable 1 { raw { file "blend.raw" offset 65536 } }
blendtable 2 { raw { file "blend.raw" offset 131072 } }
