🦋 DESCRIPTION 🦋

so like, what even is a render driver? 🧚 a render driver is a whole set of code that handles the rendering and the texture management for one particular display. it's giving "specialist for this one screen situation."

normally? there's only one 💅 but sometimes a driver has several available, each with different capabilities. so it's not always just one, okay?? don't assume, bestie.

and here's the part where it gets real: there may be none at all 😭 if SDL was compiled without render support. like, zero. the number can literally be zero. not me getting a 0 back and having to sit with that 💀
