Summary:
The x-coordinate of the area's left edge and y-coordinate of the area's
top edge are adjusted by 1px leading to a gap between the frame and
magnified area. Because area has type of QRect, we have to adjust only
coordinates of the right and bottom edge by 1 px.
Because QRectF::right() == QRectF::x() + QRectF::width(), we can use
QRectF, which leads to more cleaner code because we don't need to do 1px
adjustments.
Test Plan:
Before:
{F6235388, layout=center, size=full}
After:
{F6235439, layout=center, size=full}
