zero-length cap fix

Re-land; layout tests are suppressed and gm differences are understood.
A merge conflict prevented a automatic reland.

If the endcap is not butt, draw the endcaps even when the line
has zero length.

If the dash length is zero, generate a zero length line segment.

Treat a move followed by a close as a move followed by a zero-length
line.
