TransformControls: Scale Controls too sensitive

[msj121]

Even looking at the example given by threejs I think you will find that when one drags the scale controls the object goes to size extremes. I think for a small amount of movement the controls should be somewhat calibrated to produce smal but meaningful changes in scale

You can change the scaling amount in lines 981, 991, 992, 993 of https://github.com/mrdoob/three.js/blob/master/examples/js/controls/TransformControls.js

like this: #9312 (first comment)

or like this: http://stackoverflow.com/questions/26463872/scaling-small-objects-using-three-transformcontrols

(but this is not very convenient and it would indeed be nicer to have a possibility to adjust the scaling from outside - #5489).

@jostschmithals Sadly the new approach has been posted to remove "scalespeed" variable and I still have issues with large models that have been scaled down to still have even small changes make large impacts
