+The GTK3 port is currently designed to use system cairo for Gecko drawing.  Eventually, Gecko will probably use a different graphics system, but GTK themes will still need a system cairo context to draw.  This will require a gfxCairoNativeRenderer or similar (c.f. [http://mxr.mozilla.org/mozilla-central/source/gfx/thebes/gfxXlibNativeRenderer.cpp]) to create a system-cairo context around a surface with appropriate clipping.
-bugs with system cairo.   gfx/cairo/README has a list of patches applies to make upstream cairo work in Mozilla.  The in-tree cairo version is old, so many of these may be fixed upstream or there may be new issues.  The other option is to create a gfxSystemCairoNativeRenderer or similar to create a system-cairo context around a surface with appropriate clipping, so that GTK3 themes have a system-cairo context even in a tree-cairo build.

 We need GTK3 installed on build and test machines, and to decide whether to ship GTK2 or GTK3 ports or both.
