Gamma Correction - Changing the way all FColors are converted into FLinearColor by default. Previously all sRGB textures coming into the engine along with all other usage of FColor -> FLinearColor used a lookup table that assumed the final gamma correction would simply be pow(color, 1/DisplayGamma). However, that's not the case, we use the IEC 61966-2-1 standard on most platforms for both the scene renderer, as well as for gamma correction in Slate. In Slate you should now see an image matching Photoshop instead of being slightly darker in the lower ranges. However, because we don't want to invalidate all existing textures that users have authored, all existing UTextures have a UseLegacyGamma flag set to true, all new textures will be set to false. The flag is part of the DDC key calculation, but steps were taken so that when legacy is true, keys match existing keys to prevent universally invalidating all games DDCs just to make this change.
...
To summarize,
Old Pipeline: sRGB-Pow(2.2) -> Linear -> sRGB-IEC 61966
New Pipeline: sRGB-IEC 61966 -> Linear -> sRGB-IEC 61966

Adding Texture LOD settings to Device Profiles
- this will improve how we currently edit and override lod settings on a per device type bases.
- LOD Settings can now be set in the Device Profile Editor
- Any device profiles with no values set for LOD Settings, will use the default objects.
- These can be found in BaseDeviceProfiles.ini in the /Script/Engine.TextureLODSettings section
- Appropriate defaults set for those groups not listed.
-Other fixes
- - Incorrect with_editor check in HTML5 target platform, changed to with_engine

- Basic ASTC texture support for Metal (A8X and up) - this is experimental, and some textures are not working properly. Not exposed in the editor to enable (that will be a future changelist)
