About slowness at rendering, are you using 0.48 or a 0.48 devel with Cairo ? Cairo does the job fairly fast and you can set up multithreading in Edit/Preferences/Rendering/

Hi,
I think I'll be a little bit off topic but I don't know where to ask (my question about svg on inkscapeforum are left unanswered)
Can someone point me to reference papers (or friendly forum) about coefficients in FeColorMatrix, Fecomposite ? Something that could answer the following questions :
What are safe values ? For exemple inkscape UI allows x10 for k1,k2,k3,k4 in FeComposite, can I push to 255 ? 256 ? 1000000 ? I don't see anything in SVG spec about max values for those coeffs.
What about neg values ? When does clipping occur ? Particularly for k4.
What is the effect of a <100% opacity source or dest ? (On clipping for exemple)
I try to port svg2 PorterDuff operations in svg 1 and I often get strange results (to me) with inkscape. Is there some known bugs in rendering fecomposite with neg values in inkscape ?
Thx.
V.
Bonus question : why is inkscape so slow at rendering filters ? ;)
