Egon Elbre bce4153640 internal/stroke: fix line overlap
When the line overlaps itself backtracking exactly, e.g.

   path.MoveTo(0, 100)
   path.LineTo(100, 0)
   path.LineTo(0, 100)

then acos calculation is relatively unstable. By using atan2 it avoids
some of such problems in the calculation. Additionally, it simpliflies
the round join calculation.

Elias Naur aac53ad0b5 gpu: don't alias stroked paths with outline paths
The default renderer caches pre-processed paths for efficient re-use,
but failed to distinguish outline paths from stroke paths.

Fixes gio#294
