#2302 new bug
render caching places map in wrong place when re-enabling

Description
simple steps to reproduce with new project:
- caching ON
- load map layer
- caching OFF
- pan map a noticeable amount
- caching ON
-- the map is drawn at its original location (when loaded) AND reading the cursor location is wrong since the map extents set by the panning haven't changed.
- caching OFF
-- now the map is drawn at the previously panned location and reading the cursor location is correct.
I believe the cached map should be invalidated (dump the cache) when caching is turned off, hence the map will be totally re-drawn when caching is enabled.
