Native code to support DPI changes

[owenpshaw]

Research what, if anything, can be done with generic handlers such as Registry, System Settings, or SPI. Implement custom native code if necessary.

@owenpshaw Could you elaborate what the task is here? Is this about making the current handlers more generic, or how best to support DPI changes?

@kaspermarkus -- I believe that this refers to adding a "screen DPI" native settings handler for the "zoom text" buttons in future builds of Morphic Lite for Windows.

In MVP10, Morphic Lite uses screen resolution (e.g. 1024x768, 1920x1080, etc.) as a proxy for changing the size of text/images. Morphic Classic uses a reverse-engineered hook into Windows 10's "screen magnification" functionality (e.g. 100%, 125%, 150%, etc.). Adding that was cut from the feature list for MVP10. I believe it's going to be added with MVP20+ (which is why this ticket was created, as a placeholder to make sure it gets added).
