Support line styles for 2D/3D geometries

[shahamran]

It'll be helpful to have support for custom line styles in 2D/3D visualizations. This, together with line width and color, can convey a lot of semantic information without cluttering the views with labels.

For example, in the context of 2D tracking, we can use a solid rect for the currently detected object, and a dashed for the tracking prediction. This lets us use colors for other semantic information, like object type.

Thanks!
