Can we make the property fontSize take function values?

[nickidlugash]

Would it make any sense to do this? Is there a method which would make more sense that would enable different font sizes across different zoom levels?

+1 here. Any chance we can move fontSize and padding out of the bucket declaration and into the style declaration?

You can set a size property in text styles that can be a function, for example: https://github.com/mapbox/llmr/blob/51abc44e593a3ddc2f8dd918330f5ab7bc3bcee3/debug/style.js#L439

This only works properly for horizontal labels. I'm working on getting it to work around curves as well, but this is a bit tricky. Also, you still need a fontSize in the bucket for collision prevention. The size in the style should never be bigger than the fontSize in the bucket.

and maybe we should rename size to fontSize or vice versa.

@ansis thanks for the explanation! I'll play around with size for some horizontal labels. Would be very useful to be able to use functions for curved labels since road labels are one of the most critical features needing variable font sizing.

Starting cac61d0, font sizes as functions should work for all labels.
