TVirtualPadPainter Class Reference

To make it possible to use GL for 2D graphic in a TPad/TCanvas.

TVirtualPadPainter interface must be used instead of TVirtualX. Internally, non-GL implementation should delegate all calls to gVirtualX, GL implementation will delegate part of calls to gVirtualX, and has to implement some of the calls from the scratch.
