returns handle to device attached to offscreen world
GetGWorldDevice returns a handle to the device attached to the off screen
world specified by the off screenGWorld parameter. This device is generally the
offscreen device created by NewGWorld. If off screenGWorld was created with
the noNewDevice flag set, the attached device is one of the screen devices or the
device was passed to NewGWorld or UpdateGWorld.
If the off screenGWorld parameter points to a regular GrafPort or CGrafPort,
GetGWorldDevice returns the current device.
