Implementation complete; needs testing.
Fixed a crash bug where lldatain ::json_free() wasn't handling a NULL allocator.
Fixed some issues where the last slice of a volume was not being output and the last level of the mipchain was not being output. Cubemaps with mipmaps seem to not be generating mipmaps.
Fixed an issue where the DX10 header wasn't being flagged as present because the DDPF_FOURCC flag was being overwritten.
Fixed an issue where mipmaps were not being generated for cubemaps; updated to the latest lldatain.
