GPencil Drawing: Enable polygon smoothing

This helps to reduce jaggies from thin lines, while also resulting in nicer
lines elsewhere.

I'm not sure if it's just me, but it seems to render slightly differently to
before for 3d strokes too (i.e. they seem a bit softer). Hopefully the
difference isn't big enough to affect/degrade the art style of any projects.
