#3438: v.buffer silently ignores options depending on buffering alhorithm in use
----------------------------+-------------------------
 Reporter:  marisn          |      Owner:  grass-dev@…
     Type:  defect          |     Status:  new
 Priority:  major           |  Milestone:  7.4.0
Component:  Vector          |    Version:  svn-trunk
 Keywords:  v.buffer, GEOS  |        CPU:  Unspecified
 Platform:  Unspecified     |
----------------------------+-------------------------
 At the moment user gets no warning if some of his input parameters (i.e.
 minordistance, angle) are ignored due to use of GEOS instead of native
 buffering algorithm. v.buffer should fail with a fatal error if user has
 provided unsupported input parameters.

 Current approach of setting environmental variable to switch between GEOS
 and native algorithms is also suboptimal, as setting env on GNU/Linux is
 easy and common, while setting on Windows is uncommon thus hard. A flag
 would be better approach.
