Accessing the WndProc in a UWP Application

I was putting together a Raspberry Pi-powered bus schedule board running Windows 10 IoT the other day, when I realized that if I didn't want the thing blinding me while I tried to sleep, I needed some way to control the screen's brightness. Eventually, I found the required Windows registry keys to configure the display timeout. Unfortunately, turning the display off just made it go black–it didn't actually turn off the backlight. Some more investigation eventually yielded a method to control this particular display's backlight brightness over SPI, but now I had a new problem--I needed a way to dim the backlight when the display turned off, and to restore it when it came back on. In order to do that, I need to know when the display is turned on and off.
