      *  If pathIsMutable, then the implementation is allowed to cast path to a
      *  non-const pointer and modify it in place (as an optimization). Canvas
      *  may do this to implement helpers such as drawOval, by placing a temp
      *  path on the stack to hold the representation of the oval.
      *
      *  If prePathMatrix is not null, it should logically be applied before any
      *  stroking or other effects. If there are no effects on the paint that
      *  affect the geometry/rasterization, then the pre matrix can just be
      *  pre-concated with the current matrix.
