Labels are being lost in areas with lots of terrain

For example in Switzerland @ #7/46.294/11.920:

Simple fix would be to bump up halos on all labels, though it might look odd in areas with little to no terrain. Thoughts @almccon ?

I think slightly bigger halos will be fine everywhere. The Alps are also reminding me that we might want to town down the hillshade compositing a little bit. Does it feel like the highlights are too white and the shadows too black?

[clhenrick]

Agreed. Yes I think toning it down a bit would be helpful as well.

z10+ labels have good halos:

<= z9 halos appear to be reduced / removed for some reason:

There are some halo radii defined here: https://github.com/stamen/terrain-classic/blob/feea30ed912f0a2e6f7de492df6a242e8f56899f/labels.mss#L29-L32 but I'm not sure which labels actually use them.

If those cities are Aries labels, then here is the jump between z9 and z10 you're seeing: https://github.com/stamen/terrain-classic/blob/feea30ed912f0a2e6f7de492df6a242e8f56899f/labels.mss#L681-L695

Maybe the lower zoom halos just need to be beefed up.

After 1265f7f labels are looking like so:

Love it!
