Shaders, if deemed necessary, get attached to the node mentioned by the
top of the requirements stack. Previously an empty stack was incorrectly
assumed to mean no shaders were required, but we found out that was
wrong. We need to put shaders *somewhere*, and the root of the subgraph
we're modifying should be the best place.
With it on, which was always the case before this setting was added,
vanilla content and poorly-made mods will look acceptable, but well-made
mods will have alpha-tested meshes appear to grow and potentially gain a
weird outline as they get further away.
With it off, which replicates the 0.46 behaviour, well-made mods will
look really good, but vanilla content and poorly-made mods will have
alpha-tested meshes shrink as they get further away.
It's been bugging me that this was forced on since 0.47 released, and
I'd hoped to figure out a solution for automatic detection at some point
before 0.48 branched off, but I didn't, so now this is what we're
getting to have Tamriel Rebuilt look right.

Character preview fixes
* Adds comments explaining the less-than-obvious aspects.
* Adds comments explaining what to do when adding new stuff.
* Some fixes caused by those comments not historically existing.
* Add a TODO comment to something which may catch fire in the future.
This PR aims to solve `uniform block LightBufferBinding has no binding` messages @glassmancody has reportedly encountered since PR #3110 due to an apparent bug in OSG. While we do have to add a workaround here that adds a bit of clunkiness, #3216 should allow us to clean up these interactions a bit in the future.
With this PR we test out osg's shader define system for a somewhat harmless feature. As we can see, our code becomes more concise and efficient in this case. Most importantly, we no longer create unneeded vertex shader objects.
* avoids creating empty statesets on drawables
Currently, we attempt to skip creating state on drawable nodes when this state matches the default state. This attempt is incomplete because we still create an avoidable empty stateset in the default case.
