Vector map is blurry (especially when zooming in)
I don't really know how to explain this, but the Vector map looks more blurry than other vector maps, say, OpenStreetMap Americana.
This is more visible when zooming in. It seems like the vector map is rendered into a raster map, and that is zoomed, instead of re-rendering on every zoom step.
You can see the buildings look a little blurry:
After zooming in a little bit more, the map becomes less blurry:
I'm also not really sure how it works, but it seems each tile is rasterized. It would be interesting to use the GtkSnapshot
API to render the tiles onto the widget directly. I am very interested in helping, if provided with some pointers.
