DRAFT: Added HiDPI settings

[smakhtin]

I managed to enable HiDPI settings in the project, but looks like the whole forms layout should be updated, otherwise fonts are too big on my 150% DPI scaling settings.

I'm not experienced with Forms Designer, so hope we can collaborate on this.

I tried to reset font to system default, it works, but then all windows sizes are wrong.

Autoscaling to DPI seems working, I managed to get About form to look ok. For the main window, more work is needed.

Whatever it is, i had some scaling issue right after start.
Not exactly the same , but i think it's the same background ?
Seen on Windows 7. GRBL Plotter V.:1.7.6.0.

DPI to 100% works fine.
DPI > 100% leads to some text elements printed outside the visible area of a window.

It can also be seen in COM CNC Window.
Setting Comatiblity Flag for DPI on the Program, didnt work out to me.

DPI>100%..

DPI=100%

I also had this, when learning and playing with windows functions. Setting some flags to the window stucture when opening a window. Or was it the Item-struct ? dont exactly remember.. long ago. hope you can catch that little bug soon.
And thank you for your efforts ! Nice program.
