fixed the ordering of contour convex hull points
* partially fixed the issue #4539
An error occurred
* fixed warnings and test failures
* fixed integer overflow (issue #14521
An error occurred
)
* added comment to force buildbot to re-run
* extended the test for the issue 4539. Check the expected behaviour on the original contour as well
* added comment; fixed typo, renamed another variable for a little better clarity
* added yet another part to the test for issue #4539
An error occurred
, where we run convexHull and convexityDetects on the original contour, without any manipulations. the rest of the test stays the same
