One option is to use "Python Programmable Filter" to generate an RGBA
array in which you do the color and opacity mapping yourself. You
won't have access to the color and opacity transfer ParaView sets up,
but you can create your own internally. Not the most elegant solution
-- but a solution, nonetheless.
