The fractal routine sems to generate alot of variable heighth points but then it squeezes them into 16 colors. Id like to have that part "undone" and see if we cant get a vga smoothing look (I can provide visual examples of all of this if it helps).

I just took a quick peek at the code and if I'm not mistaken, the relevant code snippet that is responsible for this is to be found in the function "dump_color" in the file "targa.c" (very first function in that source file). Assuming I've correctly ID'd the responsible code segment, "fixing" it should be trivial.
