This allows the distant land to actually be seen when the user enables it. The
values used are replicated from MGE XE's default settings and should probably
be exposed somewhere.
By definition this is not 'Mutable state of a cell' and does not belong in CellStore.
This change should improve startup times (graph is now loaded on demand) and edits to 'pathgrid.hpp' no longer cause the entirety of OpenMW to be rebuilt.
Found on the bug http://bugs.openmw.org/issues/4165.
In original Morrowind, new clothing of the same value wouldn't replace old clothing. Tested with common and expensive clothing by selling to merchants and using the AddItem console command in original Morrowind.
In OpenMW, before this change, new clothing of the same value would replace old clothing, tested with the same methods used above.
A Warning indicates a potential problem in the content file(s) that the user told OpenMW to load. E.g. this might cause an object to not display at all or as intended, however the rest of the game will run fine.
An Error, however, is more likely to be a bug with the engine itself - it means that basic assumptions have been violated and the engine might not run correctly anymore.
The above mostly applies to errors/warnings during game-play; startup issues are handled differently: when a file is completely invalid/corrupted to the point that the engine can not start, that might cause messages that are worded as Error due to the severity of the issue but are not necessarily the engine's fault.
Hopefully, being a little more consistent here will alleviate confusion among users as to when a log message should be reported and to whom.
