Description
It was pointed out at the Great3 meeting that when we rending overlapping objects on an image, we currently just add their flux in each pixel. In reality, the foreground object blocks some of the flux from the background object.
Note: This opacity can be wavelength dependent. cf. Issue #541.

Research direction
Review the Great3 meeting context and Issue #541 first, since no implementation files or tests are named. Define how overlapping objects should account for foreground blocking, including wavelength-dependent opacity, and establish tests or examples that demonstrate the corrected rendered flux.
