[SoC] Weekly reports #6 wxNviz

[Anna Kratochvílová]

Hi,

1) What do I have completed this week?

I tested volumes in wxNviz, fixed many bugs and added volume positioning.
I improved the functionality of volumes in nviz_cmd.
I tried to implement cutting planes positioning in a more interactive way, it's not working properly
but still it may be helpful.
I added north arrow but sofar it's drawn without text because I don't know how to draw it.


2) What am I going to achieve for next week?
I'm going to implement cross sections.

3) Is there any blocking issue?
For scalebar and legend I need to draw text which is problem for me now.
