[GRASS5] antialiased vector layers in gis.m

This can't be done here, as the incoming image is already aliased. 
Antialiasing would have to go in the display drivers and it would need a way 
to be controlled (turned on and off) on at least a per-module basis.

My understanding is that this is being done on the tk canvas. None of tk 
supports transparency beyond completely transparent/opaque.
