ID 377843 - Trigger Parameter Updates Continuously from the Ramp Widget

Problem summary:

The ramp widget only triggers an update of the parameter value on mouse-up, rather than continuously as a regular slider widget does.

Steps to reproduce:

1. Create any scene with an object that has a network material applied, with a shader as a part of that network material that uses a ramp widget in its parameters tab (3Delight provides a "Ramp" shading node).

2. Live render that scene, with the material marked to trigger live render updates

3. Tweak the ramp widget and observe when live render updates occur

Expected behaviour:

The live render updates continuously when the mouse is dragged, as with a slider.

Actual behaviour:

The live render only updates on mouse-up.

Workaround:

No known workaround.

Tested versions/platforms:

All versions of Katana are affected.
