Updating to >= 0.7.20 fixes tests on macOS Catalina and newer:
# inet_pton has to be different on Mac OSX *sigh*
assert IPAddress('010.000.000.001', flags=INET_PTON) == IPAddress('10.0.0.1')
> assert int_to_str(0xffff) == '::0.0.255.255'
E AssertionError: assert '::ffff' == '::0.0.255.255'
E - ::0.0.255.255
E + ::ffff

Remove unneeded glibcLocales. Remove overrided agate-sql and agate-dbf,
as these overrides are not needed. Use pytestCheckHook instead of
overriding checkPhase. Add an upstream patch that fixes tests.
the drawing library of qcad uses qt's database abstract for sqlite.
Somehow the libqsqlite library file is not found in the default
location. As workaround it is copied to the qcad library directory.
enable/fix macOS build and add options for TBB and GL2PS dependencies
VTK integration needed a patch because implicit conversions in initializer
lists are an error in C++11, which is the default in clang 7 used by nix.
