Discussion

API naming
- Use SDL Hint naming?
- Full names? Set/GetEnvironmentVariable
- Put Override in the name?
Documentation quality
- The use of 'may' to leave for implementation flexibility may (heh) cause confusion. COnsider simpler language which describes the current implementation rather than just the API surface.

We won't need to override this in FNA3D, since we only use hints and don't interact with the CLR anyhow. Fixing it in FNA.dll will cover all the bug scenarios in this case.
