Refactoring code to set color/opacity/visibility for blocks.
This commit refactors some of the code added in recent weeks to add ability for users to set display paramaters for blocks within a composite dataset. This commit additionally adds support for changing block opacity. Blocks colors/opacities can also be overridden when using scalar coloring. The only issue is when depth-peeling gets used. In that case, point-data coloring with texture (i.e. using interpolate scalars before mapping) results in color bleeds. We need to dig into the depth peeling code to address that issue.
