Speeding up SVG filters with multicore (SMP) support
https://bugs.webkit.org/show_bug.cgi?id=43903
Some SVG filters execute a huge number of pixel manipulations, which
cannot be sped up by graphics accelerators, since their algorithm is
too complex. Using the power of Symmetric Multi Processing (SMP) we
can split up a task to smaller (data independent) tasks, which can be
executed independently.
The ParallelJobs framework provides a simple way for distributed
programming. The framework is based on WebKit's threading infrastructure,
Open Multi-Processing's (OpenMP) API, and libdispatch API.
