[Bf-docboard] Typo in documentation.

[fAX k.root]

I've noticed a typo in documentation:

In HTML: x952.html
After tip: Perspective and Orthographic, in the next sentence:
---------------
Perspective view is geometrically constructed this way: you have a scene 
in 3D and you are an observer -->palced<-- in a point O.
---------------
'palced' instead of 'placed'

PS. If it is a wrong place to report such things, please, redirect me to 
the right place.
