/*

|
|
* This is a test which demonstrates many features of the Screen
|
||
|
|
* Object rendering model:
|
||
|
|
*
|
||
|
|
* - GMR-to-screen blits from multiple GMRFBs onto multiple screens
|
||
|
|
* - SVGA3D-to-screen blits, with scaling, onto multiple screens
|
||
|
|
* - screen-to-GMR blits
|
||
|
|
* - Video Overlay with GMRs and Screen Objects
|
||
|
|
*
|
||
|
|
* For a complete test of Screen Object, several other tests are also
|
||
|
|
* necessary:
|
||
|
|
*
|
||
|
|
* - Per-screen cursors (screen-multimon test)
|
||
|
|
* - Screen creation, destruction, and redefinition (screen-multimon)
|
||
|
|
* - Checkpointing
|
||
|
|
*
|
||
|
|
* This example requires SVGA Screen Object and SVGA3D support.
