Draw Mapbox Vector Tiles with ease.
- Mapbox Vector Tiles 2.1 support
- MoveTo, LineTo, CubicTo, QuadraticTo
- Defined 256x256 canvas
- Uses floating points
- Add tags and IDs to features
- Fast encoding to MVT protobufs
- No external dependencies

mvt.LatLonXY: Converts a lat/lon to the pixel offset for a specific tile.mvt.TileBounds: Returns the lat/lon boundary for a tile.
