Ashod Nakashian e5723a22d7 wsd: update bundled headers and improve renderShapeSelection test
Unfortuantely it still fails, but this is not regression. Now
with the new patch in Core the exception is caught and so at least
the binary survives (and the API returns 0).
New unit-test added in Core to help track the issue down and fix.

Also, free the memory allocated by the API.
