* Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting.
* The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage)
* A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result.
* The global distance field is composed of 4 128^3 clipmaps that follow the camera around
* Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870.
* The global distance field currently breaks Distance Field GI
* Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

- LND will init/tear down backend DSOs cleanly.
- LND will attempt to detect the desktop environment and use appropriate backend class.
- Filters are fixed so GTK backend can parse them.
- LC_NUMERIC is forced to en_US to prevent comma vs. dot problems when parsing configs.
- Qt4 is tried before Qt5 as the latter can still crash on shutdown.

- We only need to normalize 1 axis and only rarely (when pitch is -90 or 90). ASin and ATan2 produce normalized results (as in [-pi, pi]).

Big conversion of FStrings and FNames to FText.
Version bump to move some MaterialFunction UProperty from a TArray<FString> to TArray<FText> (some Engine assets are older than being allowed to auto-convert the UProperty)
Auto conversion of FName to FText (and back) now supported (as well as TArrays of those types).
Searching categories by both the localized string and the source string is now supported in Blueprints.
