I'm wondering how everyone else does their screen edge detection.
I'm currently using Camera.pixelWidth/pixelHeight and then comparing a UIWidget's localPosition to these values to detect if the widget is close to the edge of the screen. I imagine I have to adjust the screen edge threshold depending on the current screen resolution, but that's not too big of a deal. I'm not sure if this is the proper way to do it, or if it's error prone in some way.
