    1.48 +This class provides image overlay functionality.
    1.49 +
    1.50 +Before overlay effects are applied, SetInputL should be called to specify the input overlay image.
    1.51 +
    1.52 +The overlay effect can be applied by:
    1.53 +
    1.54 +-# Begin overlay by calling BeginL(). 
    1.55 +-# Adjust overlay parameters (optional) by calling SetL(aSize, aPosition, aAngle), possibly several times.
    1.56 +-# Signal final placement of overlay by calling EndL(). 
    1.57 +	.
    1.58 +
    1.59 +Between step 1 and 3, no other effects or operations may be carried out i.e. the overlay has to be 
    1.60 +concluded/ended before proceeding to apply other effects.
