Polyline

A module for Gio to draw polylines.

It's currently a very naive implementation that draws every line segment and joins them with a circle. This solution is not suitable for transparent colors because overlapping parts are painted repeatedly resulting in an uneven coloring.

Hopefully we can fix this in the future and keep using the same api.

API

line := []f32.Point{{20, 20}, {20, 70}, {80, 80}, {110, 100}, {300, 500}}
polyline.Draw(line, width, color, gtx)

See example on how to use this to make a paint app.
