[GRASS5] r3.* and *.vtk modules roadmap

["Sören Gebbert"]

Dear developers,
i would like to inform you and to hear your opinions about a roadmap i made,
about changes on grass which i want to make in the next months,
because there is a discussion of releasing a new beta.

Roadmap:

Modules i want to modify:
r3.info
  - adding the history output flag -> same functionality like r.info [next
month]

r3.to.rast:
  - adding the option to create the resulting 2d maps with the same "2d map
region" as the source
    3d map, independently from the current region [next month]

r.to.rast3:
  - adding the option to create the resulting 3d map with the same "2d map
region" as the source
    2d maps, independently from the current region [next month]

r3.out.vtk
  - adding support for tensoric data (symmetric tensors of second order) [in
two months]
  - adding support for elevation slices between the top and bottom surface
for point AND
    cell data (this may take a while to implement) [in three to four months]

r.out.vtk
  - adding support for vector and tensoric data [in two months]

v.out.vtk
  - implementing database connection [in three months]
  - adding support for scalar, vector and tensoric cell/point data (db
columns) [in three months]
  - adding support for combined features (point + line + area + face) [in
four months]


Changes of the g3d lib:
  - get rid of a strange tiling pointer bug [in three months]
  - removing some memory leaks and errors detected with valgrind [in three
months]


Best regards
Soeren
