Further, eglQueryWaylandBufferWL accepts attributes EGL_WIDTH and
EGL_HEIGHT to query the width and height of the wl_buffer.
Also, eglQueryWaylandBufferWL may accept
EGL_WAYLAND_Y_INVERTED_WL attribute to query orientation of
wl_buffer. If EGL_WAYLAND_Y_INVERTED_WL is supported
eglQueryWaylandBufferWL returns EGL_TRUE and value is a boolean
that tells if wl_buffer is y-inverted or not. If
EGL_WAYLAND_Y_INVERTED_WL is not supported
eglQueryWaylandBufferWL returns EGL_FALSE, in that case
wl_buffer should be treated as if value of
EGL_WAYLAND_Y_INVERTED_WL was EGL_TRUE.

Change eglQueryWaylandBufferWL to take a resource pointer to the
buffer instead of a pointer to a struct wl_buffer, as the latter has
been deprecated. (Ander Conselvan de Oliveira)
Version 6, September 16, 2013
Add EGL_WAYLAND_Y_INVERTED_WL attribute to allow specifying
wl_buffer's orientation.
