Support hdpi problem (add screenshot)

[mintogo]

Hello I'm back.

(Sorry that didn't close previous my topic about simillar subject)

On previous topic I wrote about supports hdpi, and I think I didn't explain about it exactly.

So, I bring some screen shot program that I developing now.

https://ibb.co/mJsYbm
this is 1280x800 screen shot on 100% Windows 10 display magnification.

https://ibb.co/c6ZqNR
this is 1920x1080 screen shot on 100% Windows 10 display magnification.

https://ibb.co/k67zGm
this is 2560x1600 screen shot on 200% Windows 10 display magnification.
(Looks like 1280x800 on 100%)

https://ibb.co/ka2ANR
this is 3840x2160 screen shot on 200% Windows 10 display magnification.
(Looks like 1920x1080 on 100%)

All components be so smaller than 100%.

All components's position and size is absolute size.
(Except some..)

when I setArea manullay as multiply by display magnification.

(size.d_x.offset = size.d_x.offset * _scale_factor... like this
_scale_factor value may be 2.5 , 2.0 or 1.0)

all components look very blurry.

sorry about my poor English..
