Thierry Crozat b1fcd15cad GUI: Allow scaling dialog and widget sizes in constructors
The resize() function has the option to do the scaling, but
adding it to the construtor avoids having to then call resize().
Also this makes more explicit that by default the sizes are not
scaled. The reason for not scaling by default is because values
with get from the ThemeEngine are already scaled.
