[PATCH 0/2] MR4183: Draft: GdipIsVisiblePathPoint improvements and tests

[Jeffrey Smith (＠whydoubt)]

This includes a partial fix for an issue with GdipIsVisiblePathPoint uncovered by https://bugs.winehq.org/show_bug.cgi?id=55717

There are also some hacky tests to help demonstrate some quirks that are not covered by the fix.  Perhaps they will can lead to a better understanding of why the function behaves as it does.
