Undo revision 16013 by Slipyx (talk) RW clearly treats it as an int32. Better to document it that way.

Slipyx: /* Stream structure */ Reverted structure layout that lists format as 16bit and then the two 8bit values for UV sets and native geometry flags. Moved rpGEOMETRYNATIVE information to separate section.

−	'''Geometry''' is a container chunk used in [[model file\|DFF files]] as child of a [[Geometry List (RW Section)\|Geometry List]] section. The chunk itself does not store any data at all. All additional information get stored inside a [[Struct (RW Section)\|Struct]] which directly follows this one as a child. ''Geometry'' is one of the most important chunks inside a <code>.dff</code> model file. It stores geometry information for models (like the mesh and the texture maps).
