If the cached font has a different DPI than the one used in QPainter, we need to treat this the same as if other font properties have changed and redo the layout. This happened when running the QStaticText test on Wayland, because the default dpi was 100 and the QPixmap we ended up drawing to was 96. This caused the pixel size of the font to be calculated differently when doing drawText() (using 96 dpi) and drawStaticText() (using the cached 100 dpi).
