Original commit message from CVS: * docs/libs/gst-plugins-base-libs-sections.txt: Small docs fixes/updates. * gst-libs/gst/video/gstvideosink.h: Remove nonfunctional GST_VIDEO_SINK_CLOCK macro which is a leftover from the 0.9 days (GST_BASE_SINK_CLOCK, which it points to, was removed from the base sink API between 0.9.6 and 0.9.7). API: add GST_VIDEO_SINK_CAST and use it for the height/width accessor macros, so we don't do a runtime GObject type check every time we use them.
