TODOs
- cli linking
- mapping of view to tiles to show
- abstracted MapBox style JSON support
- giving render priority to features across layers (collect before render vs. direct)?
- line drawing
- support for stroke width
- support for dashed/dotted lines?
- label drawing
- support for point labels
- dynamic decluttering of labels
- centering text labels
- clipping fix when x<0 after repositioning
- multi line label
- label margin to avoid POI overlap?
- translatable raster fonts
- filled polygons
- convert polygons to triangles
- implement fillTriangle into drawille-canvas-blessed-contrib
- respect fill/line style file based setting
- lat/lng-center + zoom based viewport
- bbox awareness
- zoom -> scale calculation
- Tile parsing
- directly throw away features that aren't covered by any style
- TileSource class (abstracting URL, mbtiles, single vector tile source)
- tile request system
- from local mbtiles
- from remote url
- permanent caching of received files
- zoom while keeping center
- API
- setCenter
- setZoom
- start with zoom level which shows full vector tile
- accurate mouse drag&drop
- handle console resize
- styling
