Polygons don't render (correctly)

Hi,

Thanks for working on such an amazing package! I have a bunch of layers of data to render on county level so wanted to reduce the map loading time and came across this package.

I was checking out the demos and tried this one: https://github.com/r-spatial/leafgl/blob/master/experiments/alabama_glify.R

Everything works fine (I mean there was no error when I ran the code) but the polygons didn't show up on the map:

I modified the 100k polygons on a map demo by using my shapefile, and got into a slightly different but probably related issue that the polygons don't show different rgb colors: I'm not sure what the rgb color should be so I tried both the original rgb colors (0~255) and the original values divided by 255. Both gave the same all green-ish color on the map.

Can you pleas suggest if I misused any of the configurations? Thank you!

addGlPolygonsSrc as used in the alabama example is not actively maintained, so I'd advise to use addGlPolygons intead. I've tried yesterday and it works for me (only for a subset of the polygons though). I cannot comment on the second issue you're seeing. Maybe re-install the latest dev version and try again. I am changing things regularly these days.
