Would anyone know the reason why TControl's Scale property has been demoted to protected (at least since XE2)?

Had quite a few functions that relied on being able to change a TControl's scale, and are now forced to use an ugly typecast hack.

    I suppose this is due to the support of high DPI in VCL. Maybe you can change Form.PixelsPerInch instead (it is published)?
    Funny that in the sources there are ScaleFor*PPI*, FCurrent*PPI* and ScaleControlsFor*Dpi*, GetParentCurrent*Dpi*. Yes, I know that DPI and PPI is (almost) the same.

    T n T, really "DPI" is for printers, the ones that actually use dots. "PPI" is for screen-type devices the have real pixels. A photographer makes calibrated prints for sale would go "aaaah!". Dots <> pixels :)
