[bug#43654] [PATCH] Add perl-opengl

[Malte Frank Gerdes]

So i now managed to test if it works :) (spoiler: it does - at least on
my machine).

The patch attached to my previous mail which just adds
perl-opengl-shader and perl-opengl-image are not necessary (and also not
complete).

I did the following:
   1. ./pre-inst-env guix environment perl-opengl --ad-hoc perl-opengl 
   2. git clone git://git.code.sf.net/p/pogl/code pogl-code
   3. cd pogl-code/examples
   4. for p in *.pl; do timeout 5 perl $p; done

and this should result in all examples running successfully. This isn't
something that can be added to the test phase, isn't it?

The black screen of test.pl is a mystery (to me) though :/
