AW: AW: Implementing PseudoColor support on TrueColor screens

[Sleep]

No, that is not intentional, the original function had x = width-1 and I 
forgot to change that for clarity, and yes, the colors are converted 
perfectly, by "squashed" I mean what is happening in this image (that is 
Doom).

You see, only 1/4 of the window is being filled, instead of drawing on 
the entire window; I just thought the problem was in that function but 
that seems to be a problem unrelated to the colors. Here is the (super 
messy) original code: 
https://github.com/so-sleepy/DOOM/blob/bb4382c111ff0a83e52dd7e043884bf41c89daa0/linuxdoom-1.10/i_video.c#L769

I_InitGraphics() creates the window, I_FinishUpdate() draws the image on 
the window (you can ignore all if statements with 'multiply' inside, 
those are used to scale), UploadNewPalette() takes the game's palette 
and use that to build the lookup table.

Thank you, I will do exactly that! I will try my best to narrow down the 
issue.
