* Undo array allocation changes from #43 Doesn't work * Expand dmeter heap sizes, give names * Fix manual operator delete call in resource.cpp * Disable map rendering for now Aurora can't handle lines * Re-enable assert heap on DVD thread Should be fine? * Some basic debug groups with the new Aurora API * Allow Aurora backend to be set via CLI * Give materials debug groups * More debug groups * JKRHeap separation: array edition Pain
