+		Draws a stereo correct visibility mask.
+	</brief_description>
+	<description>
+		The visibility mask allows us to black out the part of the render result that is invisible due to lens distortion.
+		As this is rendered first, it prevents fragments with expensive lighting calculations to be processed as they are discarded through z-checking.
