 //      add contains(SkRect&)  - for clip stack
 //      add contains(SkRRect&) - for clip stack
 //      add heart rect computation (max rect inside RR)
 //      add 9patch rect computation
 //      add growToInclude(SkPath&)
 //   analysis
 //      use growToInclude to fit skp round rects & generate stats (RRs vs. real paths)

 //   rendering work
-//      add entry points (clipRRect, drawRRect) - plumb down to SkBaseDevice
-//      update SkPath.addRRect() to take an SkRRect - only use quads
-//          -- alternatively add addRRectToPath here
+//      update SkPath.addRRect() to only use quads
 //      add GM and bench
-//   clipping opt
-//      update SkClipStack to perform logic with RRs
 //   further out
-//      add RR rendering shader to Ganesh (akin to cicle drawing code)

 //      detect and triangulate RRectorii rather than falling back to SW in Ganesh

 /** \class SkRRect
 
     The SkRRect class represents a rounded rect with a potentially different
     radii for each corner. It does not have a constructor so must be
     initialized with one of the initialization functions (e.g., setEmpty,
     setRectRadii, etc.)
