Design proposal: Ability to style based on distance from the camera or legibility

[jwoodwardtfx]

We use Maplibre GL JS to draw 3D road maps. This includes road names displayed along the roads themselves. These can become illegible if the road is some distance from the camera.

Is it possible to style items such as road names so they are no longer drawn if the distance from the camera is above some threshold? That is, when they will be illegible, don't bother drawing them.

For example, in the attached (an arbitrary example taken from Bing) the roads near the camera are legible (such as Cumbernauld Road and Redford Street), but those further away (in the top left corner) are not legible. Not drawing these would both improve performance and clean up the map.

I think it's worth brining that up in the next TSC meeting, preferably with a definition of how the stylespec will look after with this addition.
