OpenGL configuration
You can disable the detection of any OpenGL extension by Allegro with a section like this in allegro5.cfg:
[opengl_disabled_extensions]
GL_ARB_texture_non_power_of_two=0
GL_EXT_framebuffer_object=0Any extension which appears in the section is treated as not available (it does not matter if you set it to 0 or any other value).
