Tools / Extract slice doesn't work on surfaces

[kephale]

Since the name Extract slice is generic I thought it might work for any napari layer. However, the widget does indicate that it only works on image layers though.

I ran into this after running into haesleinhuepf/napari-process-points-and-surfaces#84, so I started looking for a GUI way to slice the surface in time.

Yeah, extracting a slice from a surface mesh is really a different task, also presumably located in a different Tools menu in Napari. Thus, I'd say this is out-of-scope for nbatwm. Thanks the feedback anyway!

I would just follow up with a suggestion that maybe the name should be clarified. Since the Tools menu contains functions for many layer types (with very precise names in most cases), Utilities doesn't imply layer type, but Extract slice is particularly vague given that it sounds like it will continue to just work for Images.
