DebugCanvas handling Windows HighDPI scaling incorectly

Change windows DPI scaling to something other than 100% causes the DebugCanvas to display incorrect position and text size.

1. Set Windows DPI scaling to 150% or %175 (anything but 100%)
2. Create a Blueprint project
3. Create a HUD Blueprint and set it to the GameMode
4. In the HUD Blueprint, EventGraph, implement EventReceiveDataDrawHUD.
5. Off that use DebugDrawString() and HUD::DrawText() to paint identical text to same location
6. Run the app. Notice the text is not painted in the same place and not the same size
