great! The proposal on the wiki [1] is somehow focused on writing
alternative rendering engine for ps.map [2] which is currently used by
wxGUI Cartographic Composer [3]. It would be probably a good idea also
to investigate whether would be possible to write a new GRASS display
driver [4] based on Mapnik libraries. In other words replacement for
Cairo [5] driver focused on cartographic outputs. Such driver would be
written in C and would require C-API for Mapnik, I found something on
[6], but I am not sure if it would be possible to use.
