\brief Graphics frame setup
This is a high level D call. It does a full setup for the current

Note: Connection to driver must already be made.
Sets the source coordinate system to the current region, and
adjusts the destination coordinate system to preserve the aspect
ratio.
Performs a full setup for the current graphics frame:
- Makes sure there is a current graphics frame (will create a full-screen
one, if not);
- Sets the region coordinates so that the graphics frame and the active
module region agree (may change active module region to do this); and
- Performs graphic frame/region coordinate conversion initialization.
