Limiting the target setting on the level of detail generation operator to a range of 0.0 - 1.0.

Fixing an error caused by changing the settings of the level of detail generation operator.

Adding an operator to generate levels of detail from the selected object using the decimate modifier. This operator has options to control the number of levels, the amount of reduction, and whether or not to "package" the levels. Packaging means the levels of details are generated in such a way that they can easily be used as dupligroups.

Fixing a problem where libloaded objects had a NULL source for their first level of detail.

Reworking the level of detail UI so that the add button is on the bottom and a menu has been added for level of detail tools. So far these tools include a set by name operator that finds appropriately named models in the scene to use for detail levels, and a clear all operator for removing all levels of detail from an object.

Fixing a game engine crash when level of detail sources are non mesh objects (e.g. lamps, cameras, etc).

Cleaning up the game engine level of detail logic to avoid crashes with levels that have no source object defined.

The level of detail system now works in the game engine with group instances. This required the game engine to reimplement some of the level of detail logic, but not too much.

Starting support for mesh and material levels of detail in the game engine. They work for simple cases, but break in more advanced usage such as dupligroups.

Changed BKE_object_lod_update to return a bool indicating if the lod level has changed.

Moving the material level of detail switch to avoid problems with the material panel.

Group instances now update their base objects' level of detail temporarily from their own position. This allows group instances to behave properly with levels of detail.

Removing an unnecessary vector copy when updating levels of detail.

Duplicate objects no longer share level of detail settings.

The 3Dview now redraws on changes to level of detail settings. Also, changing the distance values on levels of details now causes the levels of detail to be sorted.

Fixing a crash that occurred when give_current_material was passed a NULL object.

Fixed a crash that occurred when an object being used as a level of detail was deleted.

Fixing a minor memory leak caused by not freeing the level of detail list when an object is freed.
