#3523: v.rast.stats: avoid multiple rasterization when run on multiple raster maps

     Type:  enhancement   |     Status:  new
 Priority:  normal        |  Milestone:
Component:  Vector        |    Version:  svn-trunk

 Platform:  All           |
--------------------------+-------------------------
 When computing statistics from multiple raster maps (say terrain model,
 slope, aspect, ...) for vector geometries, v.rast.stats converts the input
 vector map in every module call. That generates significant though
 unnecessary overhead.

 The simplest solution would be to allow multiple raster input (and
 multiple column prefixes).

 I would work on it during community sprint.
