+/**
+This class provides image overlay functionality.
+
+Before overlay effects are applied, SetInputL should be called to specify the input overlay image.
+
+The overlay effect can be applied by:
+
+-# Begin overlay by calling BeginL(). 
+-# Adjust overlay parameters (optional) by calling SetL(aSize, aPosition, aAngle), possibly several times.
+-# Signal final placement of overlay by calling EndL(). 
+	.
+
+Between step 1 and 3, no other effects or operations may be carried out i.e. the overlay has to be 
+concluded/ended before proceeding to apply other effects.
