<p>Looking at the proposed fix upstream[1], this change can be reverted because Qt won't generate pixelDelta for a mouse wheel.</p>
<p>I am assuming that the pixelDelta code path is there to handle high-resolution touchpads/trackpads, so what this patch does is basically tighten the condition, i.e. the code will only use the pixelDelta path if the source of the event is not a mouse, so with Qt fixed this patch should have no side effects (hopefully :)).</p>
