Description

Target Use Case

We use MapLibre to show cartoon maps of anatomical features on which neuron paths are drawn, using both plain and dashed coloured lines. The resulting map looks cluttered when there is a large number of neuron paths -- going into 3D, using Deck's ArcLayer, simply works (thanks!), nicely separating the paths. We just now need a layer with arcs drawn as dashed lines...

Proposal

Is this a case of extending the path-styles extension to ArcLayer? Or rather, what limits this extension to PathLayer?

Research direction

Start by reading ArcLayer and the path-styles extension to determine how dashed lines are currently implemented for PathLayer. Clarify whether the extension can support arcs, then define the expected dashed-line behavior for ArcLayer and add coverage for it.
