This helps to improve the accuracy of UV unwrapping and laplacian deform for high poly meshes, which could get warped quite badly. It's not much slower, doubles are pretty fast on modern CPUs, but it does double memory usage. This seems acceptable as otherwise high poly meshes would not work correctly anyway. Fixes T39004.
