[Bf-committers] Patch for Spherical UV mapping

[Ton Roosendaal]

Hi,

The 'sphere mapping' routine uses the current view to detect how to  
map, just as an extra 'control' for the user to define how mapping  
works. Not an issue, but a feature! :)

The biggest problem with this routine, was that it doesn't take care of  
creating a correct cycle. In the back you could notice an ugly seam,  
where the UV coords wrap around 360 degrees. I saw that someone (in the  
NaN days) wrote extra code to correct it. Did you test that?

I don't know why the menu option was removed... I'm fine with putting  
it back, but then I expect you to give it a good test and report on  
correct behaviour! :)
