The fix looks fine. Isn't there a timeout you can set on the unit test
rather than rolling your own inside the test? Also, even if you
interrupt the test, if the failure mode is an infinite loop in native
code then the VM you are running in is probably not going to be happy.
That only happens when the test fails, but is it worth running in a
separate VM just in case?

The trigger for the bug is that there is a translate component on the
graphics
which overflows what can be stored in a integer, and the native code we
reach
cannot handle this.
Although the sofware loops was hanging, additionally D3D and OGL on Windows
were not clipping this properly. The rendering appeared on screen when it
should have been clipped.
The fix is to add a test to see if any value overflows and then punt to
the TransformHelper code which can handle and clip this properly.
