PDFPathObject is an efficient way to draw paths on a Canvas. Do not
instantiate directly, obtain one from the Canvas instead.

PDFPathObjecta: Represents a graphic path. There are certain 'modes' to PDF
drawing, and making a separate object to expose Path operations
ensures they are completed with no run-time overhead. Ask
the Canvas for a PDFPath with getNewPathObject(); moveto/lineto/
curveto wherever you want; add whole shapes; and then add it back
into the canvas with one of the relevant operators.
Path objects are probably not long, so we pack onto one line
the code argument allows a canvas to get the operations appended directly so
avoiding the final getCode
