[cairo] Wanted features in Cairo.

You're right, Silverlight use 3 different cap positions - the start, the
end and the dash. The fourth one isn't required but I guess it could be
useful to others.

Also SL provides 4 types of cap, Flat, Square, Round and Triangle. The
last one isn't available in Cairo. Adding a new one is probably not a
big deal, but I wonder if it would be more useful(*) to provide support
for custom cap, where the user code does it's own drawing of the cap
using a provided start point and direction.


(*) E.g. libgdiplus, which is also Cairo-based, could benefit from this.

Thanks,
