Description
-----------
Hierarchy of images.
Each layer of the hierarchy is composed of 64x64 pixel tiles.
Properties
----------
Properties consist of a 4 byte identifier, a 4 byte size field
interpreted as an unsigned integer and the property data which is
"size" bytes in length. Unknown properties *must* be skipped.
