41455 2010-07-01 04:38:21 -0700 SVGRenderStyle::diff() is missing 2010-07-26 14:50:57 -0700 1 1 1 Unclassified WebKit Layout and Rendering 528+ (Nightly build) PC OS X 10.5 RESOLVED FIXED P2 Normal --- 1 zimmermann zimmermann oldest_to_newest 245253 0 zimmermann 2010-07-01 04:38:21 -0700 SVGRenderStyle::diff() is not implemented. Any CSS style change triggers relayouts, instead of repaints where approriate. On IE9 testcase http://ie.microsoft.com/testdrive/Graphics/47Atlas_zurEuropawahl/Default.xhtml, implementing this saves around 1000 relayouts when switching parties. So easy to do, high benefit, whenever SVG/CSS is combined in a dynamic fashion. 245283 1 60229 zimmermann 2010-07-01 05:50:52 -0700 Created attachment 60229 Initial patch 245334 2 60229 krit 2010-07-01 07:25:45 -0700 Comment on attachment 60229 Initial patch VectorEffect's should relayout. That doesn't happen with the current code, which depends on the current way of it's implementation. So it's fine to just repaint for the moment.
