spawn a new thread for screenshot compression and writing.  pthread side of things is loosely based on randomparticle's patch #1885849, fixed up a bunch so as not to break any existing functionality (write notifications, renderer string output, etc) and not make pthreads a mandatory dependency.  warning: not tested on any unixlike machines, YMMV.
