-To build this palette, I did the following:
-
-* Created the .asn + .obj files by hand
-* Referenced them in a .set file and asked WH40K_TD.exe to render the sprites
-* Screenshotted the output and used GIMP to create a 1x255 image with them all
-* Exported that image as an ASCII .ppm file
-* Used the `generate_palette` script to output Go code \o/
-
-Note that palette index 0 is ignored, and hardcoded to be transparent black.
-This is because 0x00 seems to be used as a record separator in .obj files, so
-can't be used as a palette index anyway.
