Summary:
When stroking paths Quartz draws incorrect line joins in flipped contexts.

Steps to Reproduce:
Run provided test project.

Expected Results:
The test project creates an image of a red and a green path. The red path is stroked into the untransformed bitmap context. Before the green path is stroked, the context is flipped. Both paths should be identical.

Actual Results:
The red path is correct. The green path has a clipped (round) line join at the bottom.

Notes:
Same behavior on Mac OS X as on iOS.
