Improve stroking of densely dashed styles
Add some auxiliary functions to cairo-stroke-style to compute
properties of the dashed patterns (period, "on" coverage) and to
generate approximations when the dash pattern is sub-tolerance.
These functions are used in cairo-path-stroke to simplify dash
patterns stroked by cairo.
Fixes dash-infinite-loop
