Capturing some differences as noted using CoreAnimationTest --> CAShapeLayer menu option. Note some of these differences may be expected gaps. I thought it was still useful to capture them.

Running the CoreAnimationTest app side-by-side on iOS and Windows will reveal the following differences:

1. Close path - activation doesn't close the line under WinObjC
2. Changing the hue on the app doesn't take effect unless the fill switch is enabled (only in fill mode) under WinObjC
3. No dashed line support
