Bug 21743 – [CAIRO] RenderPath on SVG is incomplete.

• Component: SVG
• Status: RESOLVED FIXED

[Dirk Schulze]

The support for strokeBBox and strokeContains on RenderPath in SVG is incomplete for Cairo. It misses the applying of stroke properties.

This patch applies the stroke properties to the context and makes some optimizations.

Looks fine to me.  Is WebKit GTK *still* not running DRT?  If it is, this needs a test case.  r- for lack of test case (or test case changes).  But the code change itself looks fine.

There are already test cases in LayoutTests for this patch.

strokeContains: LayoutTests/svg/custom/hit-test-path-stroke.svg
strokeBBox: LayoutTests/svg/custom/stroked-pattern.svg

strokeBBox is only used on SVG patterns with overflow="visible". Cairo lack's support for overflow="visible" currently. It is added with https://bugs.webkit.org/show_bug.cgi?id=21205. But it needs the patch for patterns on https://bugs.webkit.org/show_bug.cgi?id=21555 too.

strokeBBox don't need the pattern patch: animate-elem-26-t.svg

This test can be run by DRT now.

But DRT has some problems on svg/custom/hit-test-path-stroke.svg for strokeContains. A problem on the DRT side.
