Text wrap not working on line labels

[sheikh-iffi]

TO REPRODUCE THE ISSUE, FOLLOW THESE STEPS:

• Add text_wrap under text in any line data.
• Tried both text_wrap: 5 and text_wrap: true

RESULT:

Whole Label appears in one line

EXPECTED RESULT:

Label should appear in multiline as done in tangram JS

ENVIRONMENT:

• Tested it on 0.17.1 and both on linux and android

OTHER
Tried line break as well but that didn't work as well. Check image below

Hi, multi-line text labels are not implemented for road-lines in tangram-es - it's probably quite a bit of work to implement and computationally expensive for curved line labels. Interesting idea though.

But @hjanetzek multi-line text labels are implemented for point in tangram-es. Check Image above.
Curved line labels would be a different case.

Ah I see, if you add points along roads to your dataset you could use point multi-line labels. Would be nice and not too much work if tangram-es could generate these points but I think it's not implemented yet.

I just changed wordWrap to true here and labels on roads are now multi-line. Is there any reason that this was set to false?
