Original commit message from CVS: A rather large patch: - changed the API for the padtemplates: - remove the factories (array of pointers) for the padtemplates, properties and caps. The static array was a nice idea but converting all the property values to a gpointer was not a good idea. float properties were not possible, and casting a gint to a pointer is not very portable. The new API just uses the _padtemplate_new, _caps_new and _props_new functions to create the templates. This has the added benefit that the API is now uniform for static and dynamic templates and that the code can be made cleaner. - lots of cleanups in the way the capabilities are constructed (va_list) - lots of updates for all the plugins (new API) - docs updates (new API) - removed the videoraw docs.
