Root problem is that if
zoomreaches to18andminNumTilesis still not reached,zoomincrements to19butminX/minY/maxX/maxYdon't change. So the tiles produced are incorrect.Approach here is just to stop searching at
zoom = 18no matter what. This could optionally throw awarningin the case thati == 18L && ntiles < minNumTiles.Further, I think that
zoom = 19is valid; we could change the loop to tryi = 1:19and then stop no matter what after19...I also think we can just calculate immediately what the zoom level should be, rather than iterating like is done now... at least we can narrow the focus to within one or two zooms and then do a local search to
zoom_start +/-1... for another day
