from allegro.txt:
void text_mode(int mode);
Sets the mode in which text will be drawn. If mode is zero or positive,
text output will be opaque and the background of the characters will be
set to color #mode. If mode is negative, text will be drawn transparently
(ie. the background of the characters will not be altered). The default
is a mode of zero.
So to draw text with transparent backgrounds(zero pixels are skipped), simply
call: text_mode(-1);
