Persistent caching of vector map tiles?
Displaying vector map tiles is quite slow, because they are computed on demand using the mapsforge library.
If I zoom in and out repeatedly in the same region, the map is displayed much faster, so there seems to be some kind of caching for the computed tiles.
However, this cache does not seem to be persistent, as after a restart of Locus displaying the same region is quite slow again.
Would it be possible to (optionally) store/cache every computed tile from a vector map in a local sqlitedb, as it`s already done with online maps? With the option to define a maximum size for this cache and another option to switch it off totally (for those lucky guys with a high speed CPU in their mobile...)?
Changing the map theme and refreshing the vector map should invalidate the cache, of course.
