The spec. says this action "fills up the bounding box with the
OriginalRefFillColour".
What happens if this colour is not 100 per cent opaque? If you have
drawn anything in the object before the clear does this remain visible
through the semi transparent fill, or is anything drawn before the fill
supposed to quietly disappear so the transparency is onto the object
below the DLA object? One answer fits with the concept of "clear" and
the other with "fills the bounding box..."
Clarity please?
TIA
