While hand-crafting a SVG image and trying to achieve "fading" lines with gradients, I've discovered that Inkscape and eog (the standard Gnome viewer) render my markers very differently.
Firefox, gthumb, Epiphany and Midori all render the same way as eog, which means Inkscape might be stepping out of line.
Here's the SVG:

This renders with eog:
and with Inkscape:
The first line in the eog image and the last line in the Inkscape image show the desired behaviour.
Any ideas as how to "unify" the behaviour? I'd very much like to be able to edit the file with Inkscape, but OTOH prefer to stay with the majority of renderers.
