JavaFX 3D : TriangleMesh specification questions

 Hi Chien,

 Sorry for being so insistent, but I'm a bit confused what the final 
 smoothing group id semantic is. The RT-29236 issue title (32 bit 
 bit-set) is conflicting to what is said below (range from 1 to 31/32). 
 Also I couldn't find any range check or description in the corresponding 
 java sources.

 Please, sum up what the semantic will be in the next published early 
 access build.

 Thanks a lot, August
