Detailed Description

Helper class for building virtual texture data. This works on a set of FTextureSource objects. The idea is that if needed we can create FTextureSource without creating actual UTextures. This is why the builder should stay independent of UTexture. Things it does:

Splits texture into tiles
Preprocesses the tiles
Bakes mips
Does compression Note: Most of the heavy pixel processing itself is internally deferred to the TextureCompressorModule.

Data is cached in the BuilderObject so the BuildLayer call is not thread safe between calls. Create separate FVirtualTextureDataBuilder instances for each thread instead!

Current assumptions:

We can keep "at least" all the source data in memory. We do not do "streaming" conversions of source data.
Output can be "streaming" we don't have to keep all the data output in memory
