The LineSink
interface accepts a series of line
drawing commands: moveTo
, lineTo
,
close
(equivalent to a lineTo
command
with an argument equal to the argument of the last
moveTo
command), and end
.
A Flattener
may be used to connect a general path
source to a LineSink
.
The Renderer
class implements the
LineSink
interface.

Provides a hint that the current segment should be joined to
the following segment using an explicit miter or round join if
required.
An application-generated path will generally have no need
to contain calls to this method; they are typically introduced
by a Flattener
to mark segment divisions that
appear in its input, and consumed by a Stroker
that is responsible for emitting the miter or round join
segments.
Other LineSink
classes should simply pass this
hint to their output sink as needed.
