[PATCH 4/9] ui/gtk: Update scales in fixed-scale mode when rendering GL area

[Weifeng Liu]

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.
