[FEATURE] setting background color with aspect-ratio=keep

[jeertmans]

Description

When using aspect-ratio=keep, the background color is white.
However, this might look weird on presentations with, e.g., black background color.

I propose to add a background color option in the CLI, that defaults to black.

Screenshots

The goal is to change the color of the borders.

Example of desired output with background-color=black:

Additional information

All the changes should occur in manim_slides/present.py.

First, create a new keyword argument to App.__init__ called

background_color: str = "black"

Then, after self.label = QLabel(self), write

self.label.setStyleSheet(f"background-color: {background_color}")

After that, you need to add a new argument to the CLI (see @click.option) and pass it to the App instance.

No problem @Anmol-Ghadia ;)
I’ll probably work on this and create a PR. If you are interested, I can tag you so that you see how you could have done that?

Hi @Anmol-Ghadia, you can check #60 to see what I was roughly expecting with this issue ;-)
