Added a second patch (has to be applied after the first patch) that fixes up some comments in the uv system and renames find_nearest_uv_face to uv_find_nearest_face to be consistent with other functions.

quick suggestion for future patches: better always attach only the final patch, instead of incremental ones.

Actually I think I disagree here, the second patch is only style cleanup with no functional change, and from what I understand it is better to not mix functional change with style cleanup, no? If I had mixed them together then someone (if they follow that convention) should really seperate them out. That said, I could have made a second patch in the tracker, but as applying either patch would break the other they really are interdependent. It doesn't matter much to me, but, if I mix a bunch of style cleanup into the patches that I put here then they tend to be bigger and harder to review, and getting anyone to review patches in this tracker is hard enough, that I don't want to let anyone have an excuse not to do it. I think these patches are fairly simple to understand if you actually look at them.

If this isn't going to get reviewed because I've done the work of seperating out style cleanup from functional change, then I just uploaded another patch that mixes them together, so there really is no excuse now.

Thanks.

Don't get me wrong I've done it both ways here on this tracker, but it would be nice to know if there is an official stance on how much to include in patches. I develop using git branches and I keep most of the changes separate, but then collect them to put a patch here on the tracker, and sometimes I've changed a bunch of stuff, including style that isn't related to functional change, and it just makes the patches bigger and harder to understand, so this time I kept it separate.

I've attached another version of the patch that fixes some breakages from trunk. Also I removed turning on face centers and island select no longer uses face centers to find the nearest island. This is better because when using island select on dense meshes showing face centers it can become noisy. Also just including edges in island select was enough to fix the issue. The new file is island_select_v2.patch.

I've also made a video demonstrating this patch at: https://www.youtube.com/watch?v=Vngz1JJwm1M

Thanks.
