GPencil: Another fix for the "big square dots" problem

Strokes containing only a single point are now drawn so that they respect the
pressure values too. Previously, they were getting drawn at a fixed size based
on the thickness of strokes. Thanks to @kekeljevic for posting a screenshot which
made the problem here easy to identify!

(On a side note: Perhaps it's a combination of the drivers I'm using, or the
multisampling goodness at work, but after applying this change, the dots are
now appearing as round circles as originally intended, and can also be scaled
up quite a bit too. And that's for 3D points which couldn't be affected like
this earlier! I'm not sure what's going on here, but whatever it is, I like it ;)
