* ext/libpng/gstpngdec.c: (gst_pngdec_class_init),
(gst_pngdec_init), (user_error_fn), (user_warning_fn),
(user_info_callback), (user_endrow_callback),
(user_end_callback),
(user_read_data), (gst_pngdec_caps_create_and_set),
(gst_pngdec_task), (gst_pngdec_chain), (gst_pngdec_sink_event),
(gst_pngdec_libpng_clear), (gst_pngdec_libpng_init),
(gst_pngdec_change_state), (gst_pngdec_sink_activate_push),
(gst_pngdec_sink_activate_pull), (gst_pngdec_sink_activate):
* ext/libpng/gstpngdec.h: Complete rewrite of pngdec. It's now
very nice and handle push/pull based model. if you have filesrc
connected to it, it will do random access to load the png file.
If you have a network source that can't do _getrange, it does
progressive loading through the chain function.
* gst/alpha/gstalphacolor.c: (gst_alpha_color_transform_caps),
(transform_rgb), (transform_bgr): Fix caps negotiation correctly
thanks to Master Wim Taymans ;-)
