Dear Clemens & Jim,

As you know I am currently improving pisces performance (a lot) and I would like to compare its performance with your JulesRenderingEngine (cairo).

FYI, my last pisces patch performs a bit slower than native ductus renderer with only 1 thread (only 10-20% slower), but it very faster with multiple threads:

Note: this latest patch uses rowAA optimizations = no more RLE encoding / decoding: rowAA[32][] stores {x0 x1} {alpha sum values for range[x0; x1[ }

Could you give me instructions how to make Jules renderer work ?

Apparently JulesRenderingEngine requires xrender pipeline, cairo system library (linux) and also it loads a native library jules.

How can I get the source code / build this jules library ? or could you send me a linux x64 binary package ?
