colorwheelnative gm, to test that colors look right under all conditions.

colorwheelnative gm, to test that colors look right under all conditions.

Motivation: colorwheel on pdf-native (MacOS coregraphics) reverses Blue and Red.  I want to see if this has anything to do with image decoding.

File gm/colorwheel.cpp (right):

https://codereview.chromium.org/774713003/diff/1/gm/colorwheel.cpp#newcode59
gm/colorwheel.cpp:59: DEF_SIMPLE_GM(colorwheelnative, canvas, 128, 28) {
Might there be a more descriptive name?

https://codereview.chromium.org/774713003/diff/1/gm/colorwheel.cpp#newcode61
gm/colorwheel.cpp:61: paint.setTypeface(SkTypeface::CreateFromName("Arial",
SkTypeface::kBold));
Is there a particular reason you chose this font? Do we have any fonts that
would look the same across platforms?
