Cosmic Text for font rendering

As discussed in #1016 , I have done some testing on cosmic-text.

First of all, they have some docs that I've been exploring. And I was testing their example. They do have no_std and wasm support too according to the Cargo.toml they have.

I've noticed that the way it renders, is by drawing rectangles. Which is something I've seen for the first time to be honest. You can check it here. It gives a x,y,width,height, and color which is usually just color predefined and alpha channel being different for aliasing and stuff.

There is also another method if rectangles aren't possible: Swash Image which basically returns an image bytes to be rendered instead of individually creating rectangles. It requires some things I couldn't implement myself to be honest.

I was able to sort of hack the rectangle method in my engine

It had... not good results to be honest

Although maybe that's on me for having some issues with the engine as their examples do work and work very well. But yeah, that's my findings so far on cosmic text.
