Pull request #85 has introduced an element parameter ("ghost mode") that affects an element's opacity. We should also add element parameters that provide more direct opacity control. That will involve some design decisions:

How should the direct opacity parameters interact with indirect ones?
How should the direct opacity parameters affect edge highlighting?
Should the direct opacity parameters have different meanings for different types of elements?

I strongly recommend that the generic "opacity" of a given element be part of its "color" attribute. I do not in general see any reason to separate opacity from other color channels, and urge refactoring so that there is only a single sort of (4-channel) color entity in the software as part of the resolution of this issue.
