NAME
       make_trans_font - Makes a font use transparency. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void make_trans_font(FONT *f);

DESCRIPTION
       This function converts a font to use transparency for drawing. That is, each glyph in the font will be drawn with draw_trans_sprite, so you
       can use the same blenders as with draw_trans_sprite to draw the font. One common use of this is to load a bitmap font with an  alpha  chan-
       nel, and therefore get anti-aliased text output by using Allegro's alpha blender. Here's an example how to do that:

	  FONT *f = load_font("alphafont.tga", NULL, NULL);
	  make_trans_font(f);
	  set_alpha_blender();
	  textprintf_centre_ex(screen, f, 320, 240, -1, -1, "Anti-aliased Font!");
