[PATCH weston v2 09/17] libweston: handle the screenshoot and record bindings in weston.c

Thu Dec 4 13:01:15 PST 2014
Move the code launching the screenshooter client and implementing
the screenshot protocol out of libweston, and make screenshooter.c
a generic way to hook screenshoot protocols into weston.
