 /** \class SkCanvas
 
     A Canvas encapsulates all of the state about drawing into a device (bitmap).
     This includes a reference to the device itself, and a stack of matrix/clip
     values. For any given draw call (e.g. drawRect), the geometry of the object
     being drawn is transformed by the concatenation of all the matrices in the
     stack. The transformed geometry is clipped by the intersection of all of
