Mass tiles download optimization #124

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
If four tiles at last downloaded level (merged and halved down) give
(almost or exactly) the same tile that is above then don't save them to
cache. Then apply this to the less detailed level.
This will be useful for:
- wide areas with no details (water, forests, empty space, etc.)
- roads with no details aside.

Can as well be implemented as a "Cache maintenance" routine.
