+Subject: [PATCH 1/3] Allow applications to set next resource handle
+
+This patch adds provisions in userland to
+let apps callers set the next rendereing dispmanx resource.
+It's useful for implementing, say, a buffer carousel.

+Subject: [PATCH 2/3] wayland: Add support for the Wayland winsys
+
+* Adds EGL_WL_bind_wayland_display extension
+* Adds wayland-egl library
+* Adds wl_dispmanx_buffer protocol extension
+
+TODO: Check that platform_get_dimensions() returning swapchain_count == 1 is correct
+
+TODO: Remove the requirement of passing a valid DispmanX element handle to
+the SwapBuffers and CreateSurface RPC calls. This will remove the need to open
+a DispmanX display from the clients.
+
+TODO: wl_dispmanx_server_buffer should probably be defined in a
+private header that can be included from EGL and vc_* instead of in
+vc_vchi_dispmanx.h
