DPI scaling issues with child windows #50

Hi Hecomi,

There appears to be some issues with DPI scaling and the placement of child windows.

In legacy applications that are not DPI aware, the child window placement and scale may be incorrect.

Please try testing with something like 'Audacity' as I can reproduce the issue in this with Windows set to 150% scaling! 👍
Other applications that are DPI aware have their child windows in the correct location and scaled correctly.

In these older applications like Audacity, it also seems the cursor becomes slightly offset from the location of the raycast.
