I had to complicate the IDL bindings generation to allow passing an array of colors. Without these changes, we'd try to convert the dart object to Vector<SkColor>, which C++ thinks is Vector<unsigned>, and we'd use the wrong converter. So I added some template grease to force it to use a Vector<CanvasColor> converter. R=eseidel@chromium.org Review URL: https://codereview.chromium.org/1152963009
