QFrame does not use frame shadow in frameWidth calculation

The method QFrame::updateStyledFrameWidths() used to calculate frame width does not use the current frame shadow in setting the style options (opt.state) when calling style()->subElementRect(...).

The same code in the drawFrame method that sets the opt.state based on frameShadow needs to be copied to the updateStyledFrameWidths.

if (frameShadow == Sunken)
opt.state |= QStyle::State_Sunken;
else if (frameShadow == Raised)
opt.state |= QStyle::State_Raised;
