Graphic effects parms

The knockout option determines whether the shape of the target object is
subtracted from the underlying dropshadow effect.  In general, knockout is
better disabled because a feint halo of card color can seep through the
region where the dropshadow meets the object.  You may want to enable
knockout when your source object is translucent, so the dropshadow "stops"
at the edges of the object.

Innerglow can either begin from the center of the target object, or from
the "edge".

tmEffects doesn't include control settings for these (esoteric) options to
save space, but you can define default values for all effects settings in
the card script of the palette.
