Antialiasing is the only use of setFlags, so am cleaning up the future
PaintCanvas interface here by using setAntiAlias directly instead of setFlags.

   bg_flags.setStyle(cc::PaintFlags::kFill_Style);
   canvas->DrawCircle(circle_center, kAppListButtonRadius, bg_flags);
 
   // Paint a white ring as the foreground. The ceil/dsf math assures that the
   // ring draws sharply and is centered at all scale factors.

   const float kRingThicknessDp = 1.5f;
   gfx::ScopedCanvas scoped_canvas(canvas);
   const float dsf = canvas->UndoDeviceScaleFactor();
   circle_center.Scale(dsf);

   const float thickness = std::ceil(kRingThicknessDp * dsf);
   const float radius = std::ceil(kRingOuterRadiusDp * dsf) - thickness / 2;
   fg_flags.setStrokeWidth(thickness);
   // Make sure the center of the circle lands on pixel centers.
