 Currently we have two modules for thematic rendering vector data:

  * d.vect.thematic
  * d.thematic.area

 d.vect.thematic is a Python script which has been rewritten from Bash
 based on code from GRASS 6. This module runs several times d.vect command
 to render thematic data. This makes an integration of this module in wxGUI
 as problematic.

 d.thematic.area is a C module which use C library. This make this module
 quicker to render data and more flexible. The code can be shared eg. with
 v.colors to calculate breaks, etc. Unfortunately it's just written for
 areal features and seems to be somehow not finished.

 My suggestion is (before GRASS 7 release):

  * to move python script `d.vect.thematic` to addons
  * rename `d.thematic.area` to `d.thematic` or better `d.vect.thematic`
 (in this case to rename `d.vect.thematic` in addons to `d.vect.thematic2`)
 - any other name?

 In the future to improve C module based on functionality of Python script.

 Any comments, ideas?
