"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.

At the moment I assume both linear and radial gradients will work the same way - using a stencil buffer and some big rectangle(s) to fill with a gradient.
Thus I have a 'common' part - the part responsible for a stencil test.
