Comment 5 for bug 170321

Okay, the first part of the RFE (pressure support for Wacom)
is implemented.
Unfortunately, this is a compound RFE, can't be closed until
the other features are implemented. I've renamed it to
focus on the second set of features:

* Creation of custom vector brushes

* Custom vector brushes library with loadable presets

* Variable width/color/transparency paths

I think variable strokes is fairly challenging to implement
so am putting it at low priority (although I know a lot of
people would like to see it...)
