Implement focus ring support for image maps

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Daniel Bates]

We should add support for drawing a focus ring for image maps (i.e. implement GraphicsContext::drawFocusRing(const Path& path, ...)).

[Patch] Part 1 of 2 (GraphicsContext::drawFocusRing(const Path& path, ...))

Part 1 of 2

I thought to break this patch up into two parts so as to make it easier to look over the changes. The first part implements GraphicsContext::drawFocusRing(const Path& path, ...) and the second part includes layout tests.

I was unclear how to draw paths that describe a rectangular focus ring (e.g. <area shape="rect" ...>) with rounded corners using the Cairo/GTK API. Further investigation is needed. If anyone can save me some time with some insight/suggestions, I would appreciate it.
