icon-rotate and feature field

[wheredoesyourmindgo]

Is there a way to use a numerical value via a field property to rotate a symbol using "icon-rotate"? Maybe something similar to "text-field": "{MY_FIELD}" to populate text values for icons.

Not currently. This falls into the category of "data-driven styling" -- see #249.

Thanks @jfirebaugh. If anyone is looking for a whacky work-around for this I've been just using imagemagick to generate 360 rotated versions of the same symbol, and stuffing those into a sprite sheet using gl-style-spritify from mapbox-gl-style-spec. At that point you can simply use icon-image in the layer definition, suffixed with the relevant token.

@wheredoesyourmindgo I think for now I'm going to have to use your solution

Thanks @wheredoesyourmindgo - This is so much work for a small item (I want to show the wind direction) however your process sounds logical.

I shall be some time...
