Skip EGL surface re-creation when the buffer size is unchanged

Browse Source 
Skip EGL surface re-creation when a sequence of unprocessed resizing
requests leaves the buffer size unchanged.  In this situation, the
buffers won't be resized.  Recreating the surface without resizing the
buffers leads to screen providing incorrect information about the
buffers.
