Changeset 10545 in josm for trunk/src/org/openstreetmap/josm/data/cache

Timestamp:

Message:

Use stale cache tiles if IOException occurs

• small pretty print fixes (MemoryTileCache, TileSet)
• increase TileCache estimate (to accomodate larger TileSet's traverses when in offline mode)
• fix TileSet computations, sometimes it generated tileset of size 2 instead of 4 (for tiles inside the tile)

Closes: #13128
