Every .pcx file contains in its header RGB for the first 16 colors, and it
is read into your palette. 8-bit .pcx files also contain whole palette it
uses. If your .pcx is 24-bit, your palette will be set to 3.3.2
(generate_332_palette) which is used when you load 24-bit .pcx in 8-bit
graphic mode. You can change load_pcx (in alegro/src/pcx.c) by adding few
'if (_color_depth != 8) ...;', so you can just say 'bmp =
load_bitmap("pic.pcx", NULL);' when you want to load 24-bit .pcx. Or you can
copy/paste it, make load_pcx_24, and make those changes.

???? Don't know that.
