Provide a clear and concise description of your feature request. Why would this feature be useful? Does the feature involve the desktop build, the web build, or both?

I'd like for there to be an option to change the gamma (not just brightness) of the displayed image from ruffle.
this would be great for people with dim screens, people whose windows face the sun and brightness adjustment doesn't help (me)
and it would be great for dark horror games that make it so you cannot see where you are, let alone play the game or solve puzzles

I feel like the described scenarios would be better served by some system-level solution, rather than left to individual applications such as Ruffle.

I would agree normally, but adjusting the gamma of my monitor makes everything not ruffle completely out of whack and constant adjusting isn't very ideal...
