Make decimate modifier make use of "correct face attribute value" (Preserve UVs)

The decimate modifier makes a splendid job in detecting and preserving details while reduceing geometry that isn't completely necessary. But for some meshes, especially those that end up with a lot stretched long triangles, the modifier creates issues with UV stretching. So most of the times, not broken geometry is the issue, but the UVs.

I can imagine that the decimate modifier would profit greatly if it could preserve the UVs using this new feature.
