Prevent curved strokes in small ctms from being culled from vector surfaces

The combination of both curved strokes and ignoring the ctm in the thin
line check caused some fill-strokes in this test case to be culled.

Modify the thin line check to take the ctm into account and increase
the minimum width to 1 point to prevent curved lines such as tiny dots
from being culled.
