This section only applies to versions ≥ Cata.

This is storing really low resolution textures for use if the real file is not yet loaded or streamed. One per continent (e.g. Azeroth.tex) and some special ones (spell effects by class). Chunked structure. Internally called 'TextureBlob'.

While this is properly chunked, order is required.

TXBT

TXFN

char filenames[]; // zero-terminated, no file ending

TXMD[]

char textureData[]; // length depends on size, type and flags.
