add a puzzle game with...
Original commit message from CVS: * configure.ac: * gst/games/Makefile.am: * gst/games/gstpuzzle.c: add a puzzle game with... * gst/games/gstvideoimage.c: * gst/games/gstvideoimage.h: ... full colorspace support (that includes YUV9 and RGB16)) stolen from videotestsrc and made into something that would be a nice library for a lot of other plugins.
