Anybody knows is it possible to use shaders without actually using modern GL rendering context?
I mean use some shader code with for example: OpenGL 2.0 ?
Confusing but i have seen some old "legit" OpenGL code with some shader stuff in it.
Or its not possible because of "context" ? I mean older context can't deal with modern stuff and modern code can't affect the old 1.1 commands?
Lets say my app is using 1.1 API only and i want to add shader lighting into it. Not possible?

From what I can read around internet:

• If your app is really using 1.1 API then you will have to fall back to https://en.wikipedia.org/wiki/ARB_assembly_language
• But if you are already using Open GL 2.0 then you can already use https://en.wikipedia.org/wiki/OpenGL_Shading_Language

You can use glsl in parallel with all existing api, you just turn shader on and off with a function.
