	We refactor the surface fallbacks to convert full strokes and fills to the intermediate polygon representation (as opposed to before where we returned the trapezoidal representation). This allow greater flexibility to choose how then to rasterize the polygon. Where possible we use the local spans rasteriser for its increased performance, but still have the option to use the tessellator instead (for example, with the current Render protocol which does not yet have a polygon image). In order to accommodate this, the spans interface is tweaked to accept whole polygons instead of a path and the tessellator is tweaked for speed. Performance Impact ================== ... Still measuring, expecting some severe regressions. ...
2009-07-13	[test] Track XFAIL using expected results stored as xfail.png	Chris Wilson	1	-0/+0
	Instead of tagging the sources, which is insensitive to changes, track the known failure modes by recording the current fail as an xfail.png reference. (We also introduce a new.png to track a fresh error, so that they are not lost in the noise of the old XFAILs and hopefully do not cause everyone to fret). As we have removed the XFAIL tagging we find, surprise surprise, that some tests are now working -- so review all the reference images (as also some .ref.png now should be .xfail.png). Note: I've only checked image,pdf,ps,svg. The test surfaces report some failures that probably need to addressed in source. I've not correct the changes for win32 and quartz. Nor fixed up the experimental backends.
