Description of 'direction in IR

[Trevor Daniels]

I've a vague suspicion this has been raised before; if so, apologies.

The description of the direction property in the IR is wrong in two places. 
I think it should be corrected as follows (but I can't see where this is 
specified):

> direction (direction)
> If side-axis is 1 (or #X), then this property
                 0
> determines whether the object is placed #LEFT,
> #CENTER or #RIGHT with respect to the other
> object. Otherwise, it determines whether the
> object is placed #UP, #CENTER or #DOWN.
> Numerical values may also be used: #UP=1,
> #DOWN=-1, #LEFT=-1, #RIGHT=1, CENTER=0
                                       .
[Delete the following - only 1,0,-1 are permitted
for type 'direction']
