-- Added Decode interface to texture formats to return to PC viewable formats.
-- Added Detile interface to return textures to linear layout for relevant platforms.
-- Reworked the IBuild "DDC2" texture build usage to be more straightforward for chaining multiple build steps (i.e. Encode -> Tile -> Detile -> Decode).
-- Added UI to the texture editor to select a target platform to view.
-- Fixed a bug with DDC2 and CPU Copy textures (they didn't work at all)

Tested cooked build diff for sanity as this should only ever affect in-memory editor values.

Runtime pixel formats are named PF_ASTC_<blocksize>_NORM_RG. Use texture format name ASTC_NormalRG_Precise for encoding.

change FImage passed to TextureFormat to be const, it must not be changed becausing hashing is running threaded
remove early frees of intermediate image; this increases peak memory use

Original CL Desc
-----------------------------------------------------------------
Plumb the mip layout down to the child texture ddc key versions as certain child formats need to know mip dimensions in order to know if aspects of the build affect the textures.

Certain platforms that tile textures will tile non pow2 textures with mips different than non pow2 textures without mips, so we need to plumb down information about the mip chain to the tiling texture formats.
