(clear) should do this.

or (hint-none) (hint-on 'solid)

now it's a bit hacked, because of the negative/positive hints. for 
example, by default lighting is on, so (hint-none) switches lighting on, 
which is a bit confusing. i think (hint-none) should switch everything 
off. and there should be a 'default symbol that unites 'solid, 'lit, 
'blend, 'depth-test and 'zwrite. i think these are the default ones, but 
except 'solid, all the ones are negative hints.

best,
gabor
