Support of data expressions for lineCap in a LineLayer #2696
Description
New Feature
I have a geojson containing multiple line features with line-cap values in each feature properties and I would like to be able to set it on my map layer.
Currently, this doesn't work :
lineCap = LineCapValue(Expression.get("lineCap", style))
(In my case, the property lineCap is inside style in the feature properties)
Why
It would make it possible to make a layer on the map corresponding to more properties from the geojson and therefore be a better representation of a feature.
