High DPI support (per monitor v2)

[fowl2]

Seems to mostly work, but more of a MVP/POC.

Followed the instructions here: High DPI support in Windows Forms

On my Windows 10 22H2 machine, I can drag a window from my main display at 100% to another at 125% without it becoming blurry.

Also upgrades to .NET 4.8 - targeting .NET 4.7 didn't seem to scale tool strips correctly. This is only needed for the main project, but it would probably make sense for the others too?

Thank you for helping on this one!
If I read it correctly, it seems each and every form must be set to scale to DPI?

I did a few experiments (that I really should've recorded the outcome of) and AutoScaleMode.Dpi is what seemed to give the best results. IIRC I basically did a find and replace instead of opening each form in the designer - that may give better results.

Also works well for me on my Windows 10 computer with one screen at 100% and the second at 125%.
If some projects are already running on .Net Framework 4.8 anyway, I agree that we might as well upgrade them all
