A solution to the surface deform bind artifacts when using small scale geometry.
When the weights of the target geometry are calculated, if the geometry is too small it returns incorrect weights resulting in deformations being wrong and jumping around post bind. When the same geometry is upscaled the binding works correctly.
This patch upscales the data before weights are calculated then downscales it immediately afterwards. I was able to get clean binds on geometry that could no longer even be seen in orthographic mode it was so small.
May not be the most sophisticated solution, but should prevent the errors from occuring on pretty much any model.
