I have updated my Cairo branch today, as a step towards merging it. There is one new regression, namely feImage does not handle aspect ratio. It will be fixed before merging. IIRC, there is a problem with CMS output, the editing controls are not using custom XOR blending, and there are build failures on Windows. Does anyone remember any other bugs?
a) outline view mode
cairo-renderer r9589, OS X 10.5.8 (i386), Apple's GCC 4.2.1, no OpenMP: - cairo 1.10.2, GTK+/X11 - cairo 1.11.2, GTK+/Quartz
Outline view mode uses white to draw the outlines: they are not visible on default backgrounds (white). The color of the outline apparently is not inverted (or xor-composited (?)) when using a dark background, either.
Currently, outline mode is only usable with a solid, darker background.
b) multi-threading / OpenMP
As described earlier [1], OpenMP is not detected by the configure script when building with Apple's GCC 4.2.1 (although the man page states otherwise, and e.g. 'libgomp.a' and the omp header do exist).
Testing a build of the cairo-renderer branch using plain GCC 4.2.4 installed via MacPorts does enable OpenMP (-fopenmp), but when used in rendering, Inkscape randomly hangs (apparently waiting for something to finish(?) - see attached backtrace when interrupting Inkscape after it no longer accepts any input).
The build with GCC 4.2.4 also produced several warnings from the linker ("ld warning: can't find atom for N_GSYM stabs (...)").
I will try with newer GCC versions [2], but so far my earlier tests building inkscape trunk with GCC 4.5 and GCC 4.4 had other serious issues (crashes, or e.g. broken text rendering on canvas).
IMHO with the new renderer, we should get OpenMP working on OS X as well. Any input or help - maybe it just needs adjusted compiler and linker flags (?) - would be appreciated.
