Zooming overlay separately from the main map
Imagine we have some raster main map with zoom 7-15 and overlay with zoom 7-18.
When we zoom to level 16, main map will interpolate to 200%. That`s OK. But as I see - overlay will also interpolate to 200% although it has zoom levels 16,17,18. (If I use vector map as main map - then I see much more overlay zoom levels.) This issue will be very important when Locus will use Wikimapia overlays - there are more visible signatures on higher zoom levels.
Wouldn`t it be very difficult to implement separate zooming for main map and overlay?
In the above example we zoom in:
main: zoom14-100%, overlay: zoom14-100%
main: zoom15-100%, overlay: zoom15-100%
main: zoom15-200%, overlay: zoom16-100%
main: zoom15-400%, overlay: zoom17-100%
something like that.
