Subject: [spice-gtk] display: Trigger wheel scrolling after one 'click'

|
The scroll wheel on the mouse will trigger a smooth scroll event with a
|
|
delta of +/-1.0. The code added in 2212f05 triggers a scroll when the
|
|
delta is strictly greater than 1.0. This means that right after
|
|
connecting a client, we won't be triggering a scroll with the first
|
|
mouse wheel 'click'.
|
|
This commit adjusts the check so that we try to scroll when the delta is
|
|
equal or greater than 1.0.
