graphics/magnum*: Update to 2019.10 to unbreak the build

https://blog.magnum.graphics/announcements/2019.10/

Approved by:	yuri@ (blanket, unbreaking BROKEN port)

Add USES=xorg USES=gl, ports categories g

Add USES=xorg and USES=gl to ports in categories starting with 'g'.
While here, try to sprinkle other USES (mostly gnome and sdl) as needed.

Mark BROKEN: fails to build

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.
