Can we move properties from the bucket declaration into the style declaration?

@edenh's comment from #300

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

Is it possible to move other properties as well? E.g. "cap" and "join" for lines? That way, we can use the same bucket for roads and road casings, but specify different cap and joins in the style. Would this be more efficient, or would it be more efficient to just create two buckets (one for roads and one for road casings)?

@nickidlugash you could create two buckets in that scenario. I think it makes sense to move fontSize because it would be nice to allow for zoom-aware transitions for labels.

Are there cases where you need transitions for cap, join, etc?

In general, the bucket properties affect how the data is processed and represented when it is first loaded and the style properties are things we can change without affecting the underlying representation of the data.

By padding do you mean the minimum distance between two labels? this can't be moved out of the bucket because this affect placement which needs to be calculated when the tile is first loaded. The fontSize also affects collision detection and is needed when first processing the tile. But it should by possible to implement fontSizes as functions (#300). It might also be possible to implement padding as functions.

Line cap and join properties affect how we need to process the data, so you would need to create two different buckets.

padding is probably a much lower priority.
