/**
* The SVG spec says we have to paint stroke caps for zero length subpaths:
*
* http://www.w3.org/TR/SVG11/implnote.html#PathElementImplementationNotes
*
* Cairo only does this for |stroke-linecap: round| and not for
* |stroke-linecap: square| (since that's what Adobe Acrobat has always done).
* Most likely the other backends that DrawTarget uses have the same behavior.
*
* To help us conform to the SVG spec we have this helper function to draw an
* approximation of square caps for zero length subpaths. It does this by
* inserting a subpath containing a single user space axis aligned straight
* line that is as small as it can be while minimizing the risk of it being
* thrown away by the DrawTarget's backend for being too small to affect
* rendering. The idea is that we'll then get stroke caps drawn for this axis
* aligned line, creating an axis aligned rectangle that approximates the
* square that would ideally be drawn.
*
* Since we don't have any information about transforms from user space to
* device space, we choose the length of the small line that we insert by
* making it a small percentage of the stroke width of the path. This should
* hopefully allow us to make the line as long as possible (to avoid rounding
* issues in the backend resulting in the backend seeing it as having zero
* length) while still avoiding the small rectangle being noticably different
* from a square.
*
* Note that this function inserts a subpath into the current gfx path that
* will be present during both fill and stroke operations.
