Disable drawing of background in terminal

[trenzafeeds]

Hi everyone :)

I'm not very experienced with Ocaml, and I'd really like to figure out how to run Flitter without drawing a background in the terminal (ie use whatever the terminal background is). This is because I'd like to set my terminal to transparent so I can use Flitter as an overlay. I've already tried changing the background color in colors.ml, but afaik the RGB format used does not support transparency. If anyone can point me towards the right part of the code to modify I'm sure I can handle the rest. Thank you!
