Re: [AD] slow fonts

[Matthew Leverton <meffer@xxxxxxxxxx>]

Ran a profile on a modified ex_font.c program. It just looped for
about 10 seconds and printed three lines of text each iteration.

~~~
	while (al_event_queue_is_empty(queue))
	{	
		/* Draw red text */
		al_set_blender(ALLEGRO_ALPHA, ALLEGRO_INVERSE_ALPHA,
		  al_map_rgb(255, 0, 0));
		al_draw_textf(f, 10, 10, 0, "red %d", i++);

		/* Draw green text */
		al_set_blender(ALLEGRO_ALPHA, ALLEGRO_INVERSE_ALPHA,
		  al_map_rgb(0, 255, 0));
		al_draw_textf(f, 10, 50, 0, "green green green green green green
green green ");
	
		/* Draw a unicode symbol */
		al_set_blender(ALLEGRO_ALPHA, ALLEGRO_INVERSE_ALPHA,
		  al_map_rgb(0, 0, 255));
		al_draw_textf(a4f, 10, 90, 0, "Mysha's 0.02€");

		al_flip_display();
	}
