Introduce ``below`` option

[leplatrem]

We have two conflicting expectations regarding z-index of text.

See:

• https://github.com/makinacorpus/Leaflet.TextPath/issues/20
• https://github.com/makinacorpus/Leaflet.TextPath/issues/5

And respective jsfiddle:

@Abbe98 @fuatsengul @akshayme @p-j @solo999 do you guyz have a better idea that adding an option like this ?

Thanks for your feedback !

Thanks Mathieu,

this solution is usable for now, but we can still face the layering problem if we put intersecting polylines on the map.

current below solution :

<text1>  //this has ``below`` option
<g1>
<g2>
<g3>
<text2>
<text3>

the ideal below solution in my mind:

without below:

<g1>
<text1>
<g2>
<text2>

with below:

<text1> **below
<g1>
<text2> **below
<g2>

:+1: best solution for now. If we come up with a better solution it's very easy to replace so go for it...
