texture rendering) vtable Some of these don't work correctly or will be very slow.

## Function Documentation

void allegro_gl_destroy_video_bitmap | ( | BITMAP * | bmp | ) |

destroy_video_bitmap() overload.

Will destroy the video bitmap. You mustn't use the BITMAP pointer after calling this function.

Definition at line 308 of file videovtb.c.

BITMAP* allegro_gl_create_video_bitmap | ( | int | w,
|  | int | h
| ) |  |

create_video_bitmap() overload.

This function will create a video bitmap using texture memory. Video bitmaps do not currently share space with the frame buffer (screen). Video bitmaps are lost when switching screen modes.
