Look at Sokol or Oryol

[Jipok]

I did not know how to contact you, so I'm writing here. I wanted to know what you think about it:

Oryol: https://github.com/floooh/oryol
(great samples: https://floooh.github.io/oryol-samples/ and http://floooh.github.com/oryol/index.html)
Sokol: https://github.com/floooh/sokol
(some samples: https://floooh.github.io/sokol-html5/index.html)

These are good cross-platform libraries for working with graphics. It seems this is what you are striving for?
And if Oryol is fat, the Sokol is small and very similar to your Crow. Would you like to do porting/binding/wrapping?
In any case, I hope this will help you.

Hey, thanks for the links! Especially Oryol, looks interesting.
I'm not really sure yet where I want to go with this lib, but I might try following its structure in the future, or even a straight up port, but I want to try using the feature of nim to make it simpler.

It seems that the author decided to use nim.
