Comment 4 for bug 1153706

Ran into this issue when saving an image from Inkscape as “optimized SVG”. One gradient had gradientUnits="userSpaceOnUse" set, so the resulting SVG was not displaying as intended outside of Inkscape.

For what it’s worth, all of the following programs disagree with Inkscape (i.e. do not render the same image for test cases 1 and 2):
– Firefox
– Chromium
– GIMP
– Eye of GNOME
– GPicView
(ImageMagick, on the other hand, seems to follow Inkscape’s behavior…)

So at least from an “implementations defining standards” point of view, it seems pretty clear that Inkscape’s behavior is wrong.
