DESCRIPTION

16       This program demonstrates how to use an offscreen  part  of  the  video
17       memory  to  store  source  graphics for a hardware accelerated graphics
18       driver. The example loads the `mysha.pcx' file and then blits  it  sev‐
19       eral  times  on  the screen. Depending on whether you have enough video
20       memory and Allegro supports the hardware acceleration features of  your
21       card,  your  success  running this example may be none at all, sluggish
22       performance due to software emulation, or flicker free smooth  hardware
23       accelerated animation.
