UV Coordinates wrong for IcoSphere near poles

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Generate IcoSphere by generator
2. Apply material with texture
3. See chaos !

What is the expected output? What do you see instead?

Both poles seem to be affected.

What version of the product are you using? On what operating system?
0.1, WinXP, Ogre 1.7.2 ( Mogre )

Everything other seems to be fine, just the UV generated for Ico is not correct.

It's not really a bug... it is a well known fact that mapping a planar texture 
to a sphere produces singularities at the 2 poles. Even cartographs had to face 
this problem..
The same problem also appears with "non-ico" sphere.
And if you try to create a sphere with a modeling tool, you'll have the same 
issue.

Now for the solutions :
- Could you try increasing the number of iterations? If I remember correctly, 
it makes the seam less visible (have to check that)
- Mapping the icosphere to something else than a planar map, for example a cube 
map (that's a feature not yet implemented in OgreProcedural). You may get no 
seam at all with this method, but the texture is harder to produce.

I created issue 52, which sums up what I was saying earlier, and that would 
allow to circumvent the problem, but still requiring some manual action..
