graphics on c++

would anon please help!?
title is self explanatory, i wanna learn just the real basic/primitive stuff. like drawing lines, shapes, coloring text, things like that.

a link is fine too.

I liked the sense of hacking and adventure we had back before 3D graphics and hardware accelerators, when we would set a mode X and write our own scrolling trick, add some wavy scrolling text from a fixed-width full-colour bitmap font, yet another implementation of a starfield simulation with something we thought that made it unique, and the HSC tracker with some music ripped from somewhere, and there we go, a new intro to show our friends who wouldn't understand what the hell was that about.

Now? I've stopped writing OMG OPTIMIZED assembly shit and embraced my dynafag self. I no longer do BIOS calls and sinewave tables. Every day is about cudders and FIOC.
