Added RG_SCREEN_BACKLIGHT constant to declare the presence of a backlight and possibly its type

ducalex · ducalex · commit 2e3ff40b8a80 · 2024-07-01T12:24:18.000-04:00
Not sure yet what the value should represent. But it's safe to assume that undefined or 0 means no backlight present. This is to make ducalex#122 possible.
