[GRASS-dev] r39128 automatically choose appropriate geometry type

[Maris Nartiss]

Short note on nviz attributes - I suggest to NOT revert change that
broke this feature. I'm currently revriting attribute code, but I have
stuck in real life (work/family) and thus it will not be ready atleast
for next two weeks. It requires some redesign in OGSF, still I hope it
will be usefull also for 7.
