[gdal-dev] driver MVT, no tiles generated

[Even Rouault]

Okay, I've reproduced the problem. It is due to your input geometries being 
POLYGON Z, and the driver currently only expects XY geometries. I've just 
pushed a fix so it is more tolerant.
You can workaround the issue by adding -dim 2 to your ogr2ogr command line.
