Forms layout when using multiple displays with different scale

[dmason-mis]

I'm using a laptop display at 125% scale and an external monitor at 100% scale.

It can happen this way...
Start with VS on the 100% display.
Right click a changed file in solution explorer and access the Commit form.

(1) Form appears on the 100% display, it's resized incorrectly and the buttons are inaccessible.

• Move it to the 125% display - it then automatically lays out correctly.

OR

(2) Form appears on the 125% display, it's resized incorrectly and the buttons are inaccessible.

• Move it to the 100% display, close the form and reopen. Goto (1).

Visual Studio 2019 introduced per monitor DPI awareness. This actually broke AnkSvn, causing some windows to appear blank.

There is a good description of this problem on this page
https://blog.jetbrains.com/dotnet/2019/06/11/blank-tool-windows-resharper-visual-studio-2019-net-framework-4-8-per-monitor-dpi-awareness/

There is another description here:
https://devblogs.microsoft.com/visualstudio/a-better-multi-monitor-experience-with-visual-studio-2019/

I made the minimum fix to make AnkhSvn work, by calling the function SetThreadDpiAwarenessContext with the parameter NativeImports.DPI_AWARENESS_CONTEXT.SystemAware.

The better solution would be full support for Per-monitor DPI awareness V2 (PMv2), but at present I don't know enough about it, or about the window management in AnkhSVN to implement it.
