Toggle filter pull-tab visibility

When rendering images for e.g., journal papers it would be nice to have the option to reduce some of the visual clutter, such as the pull tabs on the filter bands.

Start by locating the image-rendering entry point and the code that creates filter-band pull tabs. Define the option's behavior so rendered images can omit those tabs, then verify that the reduced-clutter output matches the requested journal-paper use case.
