Finds a polygon enclosing the user defined mask. Inverse of poly2mask :).

This functions goal is to find a polygon which enclosures a user supplied mask. It's a kind of a complementary of Matlab poly2mask function. The difference is that all contour points are returned- without missing points for linearly related points. In order to get a 100% complementary of poly2mask all points inside straight lines should be omitted. In my case I actually need all those points, as index of ROI.
Combining mask2poly with poly2mask the user can produce a mask from a contour (line with X and Y coordinates), and vise-versa.
