My favourite use is that I can flip the correct bit in the sample state
object and forget about it ...
Gallium makes it actual work to check for the global enable (have to
search all sampler state objects), so on earlier NV cards where I only
have a global switch I just always enable seamless filtering and pretend
not to have a choice.
