 some changes applied in grass7 (the code for all branches is almost the
 same)

 > tested Spearfish's bugsites map in devbr6, looked ok. when tested in the
 old 6.4.3svn version only a thin line rendered until I moved the
 z-exaggeration slider off 0.0 to 1.0. (which seems like a nice default)

 bug in ogsf zexag guess (r56496) fixed

 since there is lots of space to the right of it for the text.

 well, nothing rendered, lots of this repeating in the terminal:
 >  (.:25449): Gtk-CRITICAL **: gtk_range_set_range: assertion `min < max'
 failed

 please test r56500

 > Spearfish geology (area) did not render at all. Perhaps it could check
 'v.info -t' via vector.vector_info_topo() and if a vector map containing
 area features is loaded pop up a warning and offer to render the
 boundaries-as-lines instead?

 It displays now boundaries by default, centroids can be activated too
 (r56495, r56497).

 > Going to the wxNVIZ Data tab at that point and trying to add a raster
 didn't work, the drop down showed the current mapset and PERMANENT, but no
 maps within them and no '>' triangle or so to click to expand them. I
 supposed that's what MarkusN experienced too, that list will only show
 raster maps already listed in the current Map Display's layer listing.
 >
 > Once I've gone back and added it to the layer list it appears, but I
 can't edit its attributes-- changing the fine and coarse resolution had no
 effect. (could the fine resolution be made a little bit (~20-30%) finer by
 default?)

 sorry, I cannot reproduce but I know that this error sometimes appears
