-/** Render Stage Screen Device abstraction.
-
-Render Stages provide this interface as an abstraction of the target screen.
-The screen may not be pixel based, in which case read back of pixel data may
-not be a reflection of what appears on the screen.  The screen might also only
-be partially readable, for example external video surfaces may be blanked out
-when a read back is done.  The intention of the CopyScreenToBitmap methods is
-to provide a means to obtain a snapshot of the entire screen for architectures
-where a composition of the screen can be done once followed by a read back
-of the entire screen, as opposed to servicing a sequence of GetScanLine calls
-which may be prohibitively expensive.
