As I have been encountering through working on Demeter's conversion to
4.1, there have been a number of 'subtle' changes in the terrain system
since its change from the "short" type to the normal signed "int" type.

Changes I have 'discovered' thus far:

* Terrain texture rotation types

AW_TERRAIN_ROTATE_NONE 0x0000 0000000000000000
AW_TERRAIN_ROTATE_LEFT 0x4000 0100000000000000
AW_TERRAIN_ROTATE_OPPOSITE 0x8000 1000000000000000
AW_TERRAIN_ROTATE_RIGHT 0xC000 1100000000000000

These values are Logical OR'd with the texture value. If the overall
value of the texture is exactly 0xFFFE (65534), a hole is placed in
the terrain.

* Attribute 'AW_TERRAIN_VERSION_NEEDED'

I have yet to have this one explained to me, but I was told some
time ago that this attribute must be set to an integer value of
'2' (via aw_int_set)

This hopefully will save some frustration for anyone else trying to
figure out what they've done to terrain now.

Yes, helpful, thank you. -cotarr
