bug:4351353 bug:8185479 Point tessellation is similar to line special case, except that we only tessellate one point (as a circle or rect) and duplicate it across other instances. Additionally: Fixes square caps for AA=false lines Cleanup in CanvasCompare, disabling interpolation on zoomed-in comparison view Change-Id: I0756fcc4b20f77878fed0d8057297c80e82ed9dc
