fdo#74702 Refactor gradient clipping functions
There are two gradient clipping functions: one uses a normal intersection
to get the symmetric difference to clip the gradient - this is used by
OS X and when printing. The other uses XOR clipping, which is an elegant
trick to implement complex clipping on graphics systems that have minimal
capabilities.
