clients/simple-dmabuf-egl: Add some notes when using direct-display
protocol
As dmabuf uses a different coordinate (top-left) system than OpenGL (bottom-left) using both direct-display with the Y_INVERT dmabuf attrib flag would result in the image being inverted (direct-display will remove the Y_INVERT flag, which caused the image to be displayed correctly). Notifies users that direct-display is in use.
