[SoC] Weekly reports #7 wxNviz

[Anna Kratochvílová]

Hi,

1) What do I have completed this week?

I implemented cross section (slices) and added this functionality
 to nviz_cmd (it's quite difficult to figure out the slice coordinates, so it's
better to use wxNviz and get the command from there).
I added transparency for constant planes (just constant value, not map, hope this is enough).


2) What am I going to achieve for next week?
I'll take a look at the scalebar and legend again. If it is possible, 
I'll try to use the 2D legend/scalebar.

3) Is there any blocking issue?
No
