I built a basic rotating cube demo with the allegro polygon and matrix
functions, but I have a problem. The cube displays as expected when in
8bit color (cube in center of the screen). BUT, when I change NOTHING
else in the program besides the color depth (to 16), the "view area"
gets cuts in half - the cube is displayed 1/4 from the left edge of the
screen, and when I apply transformations to move the cube around, it
gets clipped at half the screen width.
Also, this is in 800x600 screen mode, but the same problem exists in
640x480. The projection viewport is 0,0,SCREEN_W,SCREEN_H.
Any help would be appreciated.
