Allow all input controllers to change paint stroke settings while painting, just like the MIDI controller

Description
Until recently, I had assumed that nothing could trigger color change, for example, in the middle of painting. It has never been possible with keyboard, including the 'keyboard' controller options, nor with 'mouse wheel' controller. However, I have recently been informed that GIMP does allow MIDI controller events to trigger actions during painting ( http://wayofthepixel.net/index.php?topic=17938.msg160180#msg160180 )
This is inconsistent; as far as I can see, MIDI controllers have nothing about them that justifies unique behaviour in this situation.
Honestly, I would prefer if all input devices could trigger color / opacity / brush size / .. change during a stroke, but I can understand why this can be problematic (since it would presumably allow changing between layers or even images during painting, which could be very confusing to keep track of).
If that's not an option, then the MIDI controller plugin needs to be adjusted to conform to the behaviour of everything else (ie. no actions may be triggered during painting.)
