[Bf-committers] bump mapping - white is down & black is up???

[michael williamson]

In pretty much everything out there the convention is "white is True, 
black is False"...

in most DCC this equates to white being high (a bump) and black being 
low(a crevice)...see lightwave, 3ds max, maya and also note that this  
is consistent with the displacement map modifier in blender...
