QDockWidget: fix dock buttons size

Browse Source 
The previous fix calculated an icon size of 12 instead 10 for the icon
size when SH_DockWidget_ButtonsHaveFrame is set. This lead to a too
large icon. It was also rendered blurry because there was no native png
with 12x12 pixels so it has to be scaled.
