Bug#945516: libgs-dev: Dependencies are not necessary, should be suggests

[Thomas Loimer <thomas.loimer@tuwien.ac.at>]

Package: libgs-dev
Version: 9.27~dfsg-2+deb10u3
Severity: minor

Dear Maintainer,

libgs-dev depend on a number of lib*-dev packages - however, none of
these are necessary. All "depends" on lib*-dev packages should be
converted to "suggests".

The user who wants to compile in calls to the ghostscript-API does not
need the header files of libraries libgs itself depends on.

Yours,

Thomas
