<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>These functions are used to implement Allegro function over an OpenGL screen. </p>
<p>Keep in mind that some restictions mentioned in Allegro docs about video bitmaps and the screen do not apply when using AllegroGL GFX driver. Namely:</p>
<ul>
<li>Reading from video bitmaps is just as fast as reading from memory bitmaps.</li>
<li>Doing translucent/transparent drawing on the screen can be very fast if the source is a video bitmap.</li>
<li>Drawing from video bitmap to a video bitmap will be pretty fast on modern GFX cards with appropiate drivers installed.</li>
<li>There are dozen of places in the Allegro docs where it says that a memory bitmap must be used (drawing_mode(), polygon3d(), stretch_sprite() etc.). This doesn't apply when AllegroGL is used. You can also use video bitmaps and it will be quite fast. </li>
</ul>
