[Bf-committers] Floor constraint - patch and Windows .exe

[Roland Hess]

Made a new constraint yesterday, called "Floor". I've seen this (or a 
similar) feature asked for a dozen times in the last year.

The way it works:

1. Apply "Floor" constraint to object (or bone).
2. Choose target.
3. Choose: X,Y,Z,-X,-Y,-Z. Default is Z.

Z will not allow the constrained object to pass below the target object.
-Z will not allow it to go above the target.
X,-X,Y and -Y will do the respective actions on the global X and Y axes.

Useful for placing a "floor" or "walls" for objects and armatures. 
Apply to armature foot bones to prevent them from slipping below the 
floor.

Patch against current CVS here:

Windows binary (.exe only) here (3.4 MB - if you can patch, please do 
that instead):

Also, I don't have commit privileges, so anyone (theeth!) who wants 
to check the code and possibly commit, please feel free. Code should 
be pretty clean, as it's mostly c&p from the other constraints. I 
kept notes, too, so I can write an update to the "constraint writing" 
docs in the .org CMS.
