Subject: [PATCH] Revert "ignore wheel events in GraphicsView if mouse
 disabled"

This reverts commit f49c179275e86786af70b38b8c5085e38d4e6cce.

On Qt 5.7 ignoring the initial `wheelEvent` when `phase() ==
Qt.ScrollBegin` suppresses all intermediate events (`Qt.ScrollUpdate`)
from being delivered to the view. This makes ViewBox zooming
unresponsive.
