[window management] Touch controls should not dismiss immediately after an action

[Vesa Rautiainen]

In desktop mode 3-finger touch on an application window shows touch targets for window resizing and window move. If no further action is done they disappear after certain timeout.

Usually the window size and position change requires more than one action. For example resize horizontally + resize vertically or resize both horizontally and vertically from the corner control + set a new position for the window. That is why there should be some timeout after the user has used one of the resizing controls. Currently the controls dismiss after the first action and 3-finger tap is needed again to invoke the controls again.

I would just use the same timer as in the initial controls invocation. Just restart the time when finger released after resize action instead of full dismiss. If the user wants to dismiss the controls immediately it can be done by simple click on the window area where are no controls.
