In Firefox, we compile with warnings-as-errors and we also have
-Woverloaded-virtual enabled with GCC. GrClip.h gets included into our source
files via a public gpu header.

So even though we disable this warning in the Skia files themselves, it still
ends up getting triggered inside our own Firefox source files. GCC thus barfs
the following error when compiling Skia in Firefox:

 0:10.02 /home/lee/central/gfx/skia/skia/include/gpu/GrClip.h:25:18: error:
‘virtual bool GrClip::quickContains(const SkRRect&) const’ was hidden
[-Werror=overloaded-virtual]
 0:10.02      virtual bool quickContains(const SkRRect& rrect) const {
