Hi Eric,

Just spoken to Francois about this, looks like it relates to a commit he made 
yesterday, and an assumption in vtkTexture about the texture mode in use by 
default. He has committed a fix for this issue, sorry about that. It does 
relate to accelerating item picking, which is working really well now apart 
from a few side effects.
