[Inkscape-user] NEW: faster blur

I committed the patch by Jasper which implements a faster blur algorithm, so now the Gaussian blur must be noticeably faster in the SVN trunk.

Everyone using gaussian blur, please test the new code with regard to:

- any especially bad artefacts? (as before, lowering quality in Preferences > Filters introduces some artefacts, but they look reasonable, I think even nicer than with the old algorithm)

- how much faster it is on your images? (test on different zooms and with export; we need some estimates to put into the release notes)

- is the range of quality/speed settings adequate? or would you like to have a still faster/lower quality step?

- any other problems?
