Bug#616736: opencascade: please update to 6.5.0

[Denis Barbier]

Package: opencascade
Version: 6.3.0.dfsg.1-6
Severity: wishlist
Tags: pending

Hello,

I updated opencascade to 6.5.0 in our git repository.
It builds fine, but this required a lot of work and I do not have time
to perform extensive testing.
There is one issue which has to be fixed before uploading,
libopencascade-foundation-6.5.0 depends on libx11-6 and libxt6, one
has to check why those dependencies have been introduced, and fix
them.
