Re: [Inkscape-devel] Cloned gradient bug fix

Krzysztof and Tomasz, could you have a quick look at this. I think gradients might need to be treated like clips, masks, and patterns.

As for representation in SP Tree, patterns and gradients work the same way. SPPattern refactoring affects rendering and NR tree only.

While working on GSOC i also stumbled upon the problem that when paint servers are deleted and added to SP tree, invalid memory accesses (including malloc internal data corruption) happen.
