I would have expected for COLOR_MANAGED_USER_LABEL and
COLOR_MANAGED_USER_LABEL_BACKGROUND to be handled either here or in ThemeService
but not both.

[Adrian Kuegel, 2013/07/22 12:58:08]

The reason I do it here and in the ThemeService is: I want the managed user
theme have these specific values, but if some other theme is installed (what we
now want to support in M30), we need to derive the colors from other properties.
So the code in ThemeService is there to support other themes, and the code here
is for the special case of our theme. Unfortunately I don't see a way how to
calculate the colors we want for our theme from the other color properties which
would work in general.

+    *color = SK_ColorWHITE;
+    return true;
+  }
+  if (id == ThemeProperties::COLOR_MANAGED_USER_LABEL_BACKGROUND) {
+    *color = SkColorSetRGB(108, 167, 210);
+    return true;
+  }
+  return false;
+}

+    id = IDR_MANAGED_USER_THEME_FRAME_INACTIVE;
+  else if (id == IDR_THEME_TAB_BACKGROUND || id == IDR_THEME_TAB_BACKGROUND_V)
+    id = IDR_MANAGED_USER_THEME_TAB_BACKGROUND;
+  return rb_.GetNativeImageNamed(id);

Return an empty gfx::Image if HasCustomImage() == false.

Done.
