Subject: [PATCH] cubestorm: enable double buffer on linux

Like noof, at least on Fedora 22 x86_64
while cubestorm shows some graphics on xscreensaver-demo
window, on full screen saver mode cubestorm
shows just a blank screen, like as written
on launchpad #1390304.

Enabling double buffering seems to make
cubestorm show graphics on save mode like
noof.
