[046/906] * sys/glsink/BUGS: * sys/glsink/Makefile.am: * sys/glsink/gstglbuffer.c: * sys/glsink/gstglbuffer.h: * sys/glsink/gstglconvert.c: * sys/glsink/gstgldisplay.c: * sys/glsink/gstglfilter.c: * sys/glsink/gstglfilter.h: * sys/glsink/gstglfilterexample.c: * sys/glsink/gstgltestsrc.c: * sys/glsink/gstglupload.c: * sys/glsink/gstopengl.c: Remove code that handles non-texture buffers. Add a GstGLBufferFormat type that corresponds to how to use the texture, not the original video format. Convert gstflfilter.c into a base class, add glfilterexample and glconvert elements. * sys/glsink/color_matrix.c: Minor ramblings about color conversion matrices.
