Fixes Cg

This patch fixes bugs in CanvasStyle, GraphicsContextCg,
RadialGradientAttribute. Now the Cg-implementation should be able to display
Canvas as well as SVG-Gradients.
I fixed Cairo too. But the modification causes some problems, eg.
http://www.w3.org/Graphics/SVG/Test/20061213/htmlObjectHarness/full-pservers-grad-16-b.html
-> Segmentation Fault (The gradient with the false stopColor) and I can't
destroy the pattern for drawing gradients, as long as the gradient is not
destroied.
I made a build-fix for Qt but haven't updated SVG yet. gradients and patterns
on Canvas still end up in an Segmentation Fault. Perhaps some of the Qt-folks
can help out.

The big patch should be splitted in to different patches.
