NAME
al_get_opengl_fbo - Allegro 5 API
SYNOPSIS
#include <allegro5/allegro_opengl.h>
GLuint al_get_opengl_fbo(ALLEGRO_BITMAP *bitmap)
DESCRIPTION
Returns the OpenGL FBO id internally used by the given bitmap if it
uses one, otherwise returns zero. No attempt will be made to create an
FBO if the bitmap is not owned by the current display.
The FBO returned by this function will only be freed when the bitmap is
destroyed, or if you call al_remove_opengl_fbo(3) on the bitmap.
Note: In Allegro 5.0.0 this function only returned an FBO which
had previously been created by calling al_set_target_bitmap(3).
It would not attempt to create an FBO itself. This has since
been changed.
