+ Every graphics operation in LyX should be made by this class. It will
be initialized and managed by the Screen class, and will be passed
as a parameter to inset.

It hides low level windows system parameters so insets and other
clients don't have to worry about them and we can control graphics and
GUI toolkit dependent drawing functions inside this single class.
