Reactivate size slider in Red Eye Reduction tool
While porting from KIntSpinBox to QSpinBox in 4efdfcdaef68 the
connection between the size slider and the spinbox got lost and
effectively disabled the slider.
This patch adds the signal/slot connections between both widgets
again and restores the functionality.
- Open Gwenview in View Mode
- Enter Red Eye Reduction tool
- Click in image to activate size option
- Check if slider and spinbox are synchronised
