NAME
       al_get_opengl_texture_size - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro_opengl.h>

              void al_get_opengl_texture_size(ALLEGRO_BITMAP *bitmap, int *w, int *h)

DESCRIPTION
       Retrieves the size of the texture used for the bitmap.  This can be
       different from the bitmap size if OpenGL only supports power-of-two
       sizes or if it is a sub-bitmap.  0's are returned if the bitmap is not
       an OpenGL bitmap.
