Control properties by zoom level?

[nickidlugash]

Is there a way to control properties by zoom level, other than assigning functions to numerical values? E.g. if you wanted to completely change the color of a feature at a certain zoom level? Not a big deal right now, since a lot of the properties this would be most useful for are not supported (like multiple font stacks or text transform), but I think this would eventually be important.

This is easy from a rendering perspective, but the tricky part is to find a syntax that doesn't unnecessarily complicate the stylesheet. Right now, you could do this as a stops functions, with two stops at the zoom level, the first specifying the previous value and the second with the new value.

@kkaefer Thanks! What is the syntax for writing stop functions? Will try it out and then describe more specifically here the use cases where we will need another method.

@kkaefer what arguments does the stop function take? Do you have an example you could share?

[kkaefer]

The syntax is: ["stops", {z: 0, val: 4}, {z:3, val: 8}, ...]. It exponentially interpolates between two stop values.

Stops work for colors now, so I think the issue can be closed.
