OpenGL bindings for C#

Usage with SDL library:

using SGE.GL;
<.....>
var window = SDL_CreateWindow(title, SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, width, height,
				SDL_WindowFlags.SDL_WINDOW_OPENGL);
var context = SDL_GL_CreateContext(display.Handle);
SDL_GL_MakeCurrent(window, context);
// init functions for current context:
var openGl = new OpenGL(SDL_GL_GetProcAddress);
// set to current
OpenGL.Capabilities = openGl;
// here you can use opengl. for example:
glClearColor(0.5f, 0.5f, 0.8f, 0.0f);
glClear(GL_COLOR_BUFFER_BIT);

with multiple contexts just make current OpenGL instance:

// set current
SDL_GL_MakeCurrent(windowHandle, contextHandle);
OpenGL.Capabilities = openGl;
// unset
SDL_GL_MakeCurrent(IntPtr.Zero, IntPtr.Zero);
OpenGL.Capabilities = null;
