💅 REMOVEDTYPES — the removedTypes page, bestie (3G, OpenGL vibes) ✨

okay so real talk, this one's a little history lesson and it's lowkey fascinating, come sit with me 🫶

✨ NAME ✨

removedTypes — it literally describes the types that got removed and replaced in the OpenGL API when OpenGL 4.2 showed up 👑

🌸 DESCRIPTION 🌸

So here's the tea 🍓: back in the May, 2012 glow-up of the OpenGL 4.2 Specification, every single API that was using the types GLclampf and GLclampd got edited to use GLfloat and GLdouble instead — respectively, no cap. 💫

And they didn't just swap the names and dip. They added language to the Specification saying these parameters have to be clamped — but when it's required, at use time, not at specification time. Timing matters, periodt ⏰

Why is this iconic? Because now you can specify parameters in ranges that actually make sense for non-fixed-point framebuffers — that's your integer formats and your floating-point formats 💖

And the best part, the part that makes me emotional 😭: the change does not require any changes to user code calling these functions. Not one. Because:

  • the actual underlying types are identical — literally twins 👯
  • the behavior is externally unchanged — vibe check passed 🌈
  • the header files continue to define the old types for compatibility with older code — they're keeping the old ones around out of pure loyalty 🥹

so basically: nothing broke, nobody had to touch their code, and everything's still slaying. we love a backwards-compatible queen 👑
