dependency on libGL (menpo3d -> CyRasterize)

Just trying to get landmarkerio-server running on a fresh VM of 14.04 and we hit an error after

conda install -c menpo/channel/master landmarkerio

Traceback (most recent call last):

Problem is the server I'm using is headless -> no X11.

apt-get install libgl1-mesa-dev libglu1-mesa libxrandr2 libxi6

needed to fix, but this drags in X11 that we really don't need for serving landmarks...

Just fix the import chain

Fixed here: https://github.com/menpo/cyrasterize/commit/6fa28a2959c834c4da0e2e22a2a7c57b48402075 and released cyrasterize 0.2.2.

Menpo3d 0.1.0a3 released to depend on this and include a handful of other bugs that were present.
