Owen W. Taylor afceea3fe6 Add a built-in screencast recording facility
For development and demonstration purposes, it's neat to be able to
record a screencast of gnome-shell without any external setup.
Built-in recording can also give much better quality than is possible
with a generic desktop recording, since we hook right into the paint
loop.

src/shell-recorder.[ch]: A general-purposes object to record a Clutter
 stage to a GStreamer stream.
src/shell-recorder-src.[ch]: A simple GStreamer source element (similar
 to appsrc in the most recent versions of GStreamer) for injecting
 captured data into a GStreamer pipeline.
src/test-recorder.c: Test program that records a simple animation.

configure.ac src/Makefile.am: Add machinery to conditionally build
 ShellRecorder.
tools/build/gnome-shell-build-setup.sh: Add gstreamer packages
 to the list of required packages for Fedora.

js/ui/main.js: Hook up the recorder to a MetaScreen ::toggle-recording
 keybinding.

/**
* ShellRecorderSrc:
*
* shellrecordersrc a custom source element is pretty much like a very
* simple version of the stander GStreamer 'appsrc' element, without
* any of the provisions for seeking, generating data on demand,
* etc. In both cases, the application supplies the buffers and the
* element pushes them into the pipeline. The main reason for not using
* appsrc is that it wasn't a supported element until gstreamer 0.10.22,
* and as of 2009-03, many systems still have 0.10.21.
