Inputs

tdt	a texture-data-target
level	an integer

Outputs

byte-array

a byte-array

Word description
Reads the entire compressed image for the levelth level of detail of a texture into a new byte-array. The format of the data in the byte array is determined by the compressed-texture-format of the data originally allocated by allocate-compressed-texture for the texture.
