Interesting project, but you still need to hook it up to a backend to create a window to draw pixels on. SDL is likely the most portable library to do that; you could substitute fbdev, DirectX, wgpu, glfw, win32, metal, and so on.

The point is, once you have a window and a putpixel (or even better, surfaces and blitting), the rest is easy to handcraft. A standardised library would of course help.
