[Fluxus] commits - (hint-on), (hint-off)

[gabor papp]

hi all,

the (hint-on), (hint-off) functions that we have been talking about are 
added. i changed the negative hint symbols to positive ones. the symbols 
are: solid, wire, normal, points, anti-alias, box, vertcols, origin, 
cast-shadow, depth-test (hint-ignore-depth), depth-sort, lazy-parent, 
cull-ccw, cull-cw, wire-stippled, sphere-map, frustum-cull, normalise, 
blending (hint-noblend), zwrite (hint-nozwrite), lit (hint-unlit). the 
symbol 'all can be used to switch on or off all hints. comments or 
corrections are welcome.

best,
gabor
