Fix sizeHint of QProgressDialog to have enough space for window margins
Some styles, notably QMacStyle, use different margins for widgets and for windows. For these margins to be returned correctly, we have to tell the style that we want them for a toplevel widget. This was done correctly when laying out the dialog, but not when calculating the sizeHint, leading to a default size of the dialog that was too small to fit the text. As a drive-by, change variable names in the sizeHint method to be a bit more readable.
