+Subject: [gst-bad-1.8] gstwaylandsink: Add DRM support on waylandsink
+
+Add wl_drm interface on waylandsink.
+The following features are supported:
+1. Support for mouse drag and drop.
+2. Support for video cropping
+
+The following bug fixes identified earlier have been picked:
+1. Consolidate header files to avoid circular dependency
+2. Fix bug reported on waylandsink incase of same process looping
