We currently apply a strange algorithm to `LightManager::mStateSetCache`. For some reason this algorithm inserts hashed keys into `std::map` in a way that fails to handle hash collisions and exhibits worse lookup complexity than `std::unordered_map`. With this PR we just use `std::unordered_map` here.

resets state updater to apply light settings
With this PR we achieve the same effect with fewer lines of code.
* fixes LightSource logic errors
We currently update `LightSource::setActorFade` in `TransparencyUpdater`. There are several logic errors inherent in this approach:
1. We fail to update `LightSource::setActorFade` for off screen actors because their `TransparencyUpdater` cull callback is not invoked.
2. We fail to update `LightSource::setActorFade` in the instant that a `TransparencyUpdater` is removed.
3. We fail to update `setActorFade` when an `mExtraLightSource` is created after calling `Animation::setAlpha`.
With this PR we avoid such issues by updating `LightSource::setActorFade` in `Animation::setAlpha` and `Animation::addExtraLightSource` instead.
This PR fixes an assertion introduced by #3211. For some reason my build originally did not contain assertions despite passing `DEBUG` into cmake, but after deleting `CMakeCache.txt` I have now hit the assertion @glassmancody reported as well.
With this PR we restore the previous order of `ESM::Dialogue` entries implicitly changed by PR #3197. In the future we may want to consider additional verification and documentation of `mShared` order inconsistencies. We might additionally consider applying this sorting in the particular code that requires it.
This PR aims to start addressing `ESM` design issues that have silenced errors we incorporated into groundcover `ESM` loading approaches.
- We move the resolution of `parentFileIndices` from `ESMStore` to `ESMReader` as suggested in a `TODO` comment.
- We improve a highly misleading comment which downplayed the significance of `parentFileIndices`.
- We document important preconditions.
- We move a user facing error message to the highest level and improve its context.
- We remove an inappropriate `setGlobalReaderList` method. We now pass this reader list into the method that requires it.
- We remove a thoroughly pointless optimisation of `Store<ESM::LandTexture>`'s construction that has unnecessarily depended on `getGlobalReaderList`.
There should be no functional changes for `master`, but this PR should remove an issue blocking PR #3208.
With this PR we restore @elsid 's optimisations of countRecords we have unintentionally discarded in PR #3197. In addition, we give it a more appropriate name and add comments concerning its peculiar background.
With this PR we apply `lightMask` to a `Transform` node we create specifically for a light. This mask will allow us to stop traversing such nodes sooner and avoid costly processing associated with `Transform` nodes in the cull visitor.
I have been informed by @akortunov that my addition of `Groundcover::getViewDistance` is not working in some cases. Investigations revealed that some `ViewData` code interacting with my additions had been quite thoroughly optimised in a way that was not sufficiently documented and interfered with the new feature. With this PR we repair `getViewDistance` while preserving such optimisations and add a necessary comment to avoid issues in the future. In addition, we now rebuild views when the global `mViewDistance` changes.
With this PR we refactor `SceneUtil::KeyframeController` not to require `virtual osg::Callback` inheritance. I suppose such `virtual` overhead is not justified here because it negatively impacts many other classes we derive from `osg::Callback`.
