"Delegating" part of TGLPadPainter.

Line/fill/etc. attributes can be set inside TPad, but not only there: many of them are set by base sub-objects of 2d primitives (2d primitives usually inherit TAttLine or TAttFill etc.). And these sub-objects call gVirtualX->SetLineWidth ... etc. So, if I save some attributes in my painter, it will be mess - at any moment I do not know, where to take line attribute - from gVirtualX or from my own member. So! All attributed, ALL go to/from gVirtualX.
