Eeeek! No way! If anything you want to have an abstraction layer on top of
this to provide a unified view on all of the underlying specifics, such as
different APIs (OpenGL, Direct3D, RAVE come to mind) as well as API specific
differences (now is that OpenGL 1.1 or OpenGL 1.0 with a vertex array
extension or is it plain 1.0 or what).

Not a shame - just the appropriate punishment ;-)
