119217 - Mozilla should do some clipping when not rendering the whole svg

Status: RESOLVED FIXED

(Core :: SVG, enhancement)

Description

[mop]

The URL shows a zoom&panable map. If you try to zoom (the inner buttons) you
will see that it gets slower the more you zoom in. When zoomed in it renders
only a small subset of the elements but it's actually slower than when zoomed
out and rendering a huge amount of elements. mozilla should recognize that only
a few elements are in the svg area and forget about the rest for a moment. This
would be a great speed improvement.

Mass reassign of SVG bugs that aren't currently being worked on by Alex to
[e-mail]. If you think someone should be assigned to your bug you can
join the #svg channel on mozilla.org's IRC server ( irc://irc.mozilla.org/svg )
where you can try to convince one of the SVG hackers to work on it. We aren't
always there, so if you don't get a response straight away please try again later.

this URL is broken, hence there is no test case

Trunk now does throw out geometry that is outside the paint area.
