[Stable-10.0.3 06/39] ui/gtk: Update scales in fixed-scale mode when rendering GL area

[Michael Tokarev]

From: Weifeng Liu <weifeng.liu.z@gmail.com>

When gl=on, scale_x and scale_y were set to 1 on startup that didn't
reflect the real situation of the scan-out in free scale mode, resulting
in incorrect cursor coordinates to be sent when moving the mouse
pointer. Simply updating the scales before rendering the image fixes
this issue.
