Add a Gaussian smoothing operator to supersede the current smoothing operator in the graph editor. Advantage over the current implementation: * Supports modal operations * Is independent of key density * More options in the redo panel * More predictable Impulse Response Option in the redo panel to change Filter Width: How far out on each side of a key the code checks to average key values Sigma: The shape of the bell curve, lower values make a sharper bell curve reducing the smoothing effect. Too High values will make the code behave like an average filter as the curve in the -1/1 range will almost be flat. On a technical note, the operator needs to store additional data when running in modal to avoid allocating/deallocating data on every modal run. For that reason the `tGraphSliderOp` struct has been extended with `void *operator_data` and `void (*free_operator_data)(void *operator_data)`. The former is the data and the latter is a function responsible for freeing that data. Pull Request: blender/blender#105635
