The BevelFilter, BlurFilter, ColorMatrixFilter, ConvolutionFilter,
DisplacementMapFilter, DropShadowFilter, GlowFilter, GradientBevelFilter,
and GradientGlowFilter classes all extend the BitmapFilter class. You can
apply these filter effects to any display object.
You can neither directly instantiate nor extend BitmapFilter.
