## Detailed Description

Allegro-OpenGL interfacing.

This sorts out having Allegro and the OpenGL library sharing a window, and generally cooperating.

Definition in file alleggl.c.

## Variable Documentation

BITMAP* allegro_gl_screen

Direct-mode GL `screen' bitmap.

If you draw to this bitmap (using supported Allegro functions) your calls will be converted into OpenGL equivalents and appear on the screen (or backbuffer).
