fix #3882

[petrasovaa]

wxGUI: g.pnmcomp needs to use the same size as the indivually rendered maps

[petrasovaa]

I only catch the weird exception, it seems to be working otherwise. I couldn't find a proper solution to this.

I found the problem (should have paid more attention to the error message). I disabled the setlocale code for windows (there doesn't seem to be any problem on linux), but I suspect there was a reason the code was there, so it needs to be tested... Specifically, the problem comes up if you switch to 3D view or digitizer.

with the changes in core/render.py, nviz/wxniz.py and vdigit/wxdisplay, vector digitzing of points, lines and areas works again.
