Bug#883307: mutter: missing gles2 support since clutter integration

[Alban Browaeys]

Package: mutter
Version: 3.26.2-1
Severity: normal

Dear Maintainer,
Since upstream embedded a forked of clutter/cogl and the gles2 flag was
not ported from clutter/cogl to mutter, we lack gles2 support.

The other issue was fixed upstream and have reached debian a while
ago so this is the last stone on the gnome side.
This was https://bugzilla.gnome.org/show_bug.cgi?id=771636
included in 3.24.1.

Attached is a diff to debian/rules that add --enable-gles2 .
Tested on Intel Haswell (glx + gnome-shell wayland) and ARM Odroid U2
(gles2 over Mali blob + gnome-shell Xorg - custom kernel and xorg ddx)
