/*
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.
