GIMP spin scale relative movement feels unresponsive
Submitted by João Sebastião de Oliveira Bueno
Created attachment 212295 Implements acceleration of value change for broad mouse movements in relative mode of gimp spin scale widget.
When using the new spin scales with the relative movement feature, it moves in a linear way. Since it is designed primarily to allow for fine adjustment of the values, it is rather fine for small adjustments.
However, when moving the pointer fast, in a broader movement, the linear speed of the movement feels slow. Even if the mouse cursor accelerates, the pointer still has to go too far away from the control for one to have a nice feedback in the change.
The attached patch proposes to lessen the feeling of unresponsiveness to broad movements by accelerating the value change when the mouse movement is wider than a threshold (currently set to 1/4 of the widget's width)
