I am trying to print out some text over a bitmap. If I use textout(), the
text appears in the color I specify, but with a black background, thus
changing the background picture slightly. According to the Allegro docs,
if you specify a negative text_mode(), the text will be printed without
altering the background pic. But, my code which looks a little like,
text_mode(-200); /* I've tried other negative numbers as well */
textout(screen,font,"Hello world!",0,0,255);
This causes some weird things to happen. Once the mouse suddenly was
constrained to a certain section of the screen (I have no code for this)
and other times the entire screen goes black with a cursor flashing in
the top left corner. The particular part of the picture I am trying to
write on is white, and I want black letters,
