XOGL

====

Minimal OpenGL loader for X11.

XOGL consists of three functions:

- `xogl_init()`: Initialize an OpenGL context and load OpenGL functions.

- `xogl_swapBuffers()`: Swap front and backbuffers. Use after finished drawing.

- `xogl_destroy()`: Destroy the OpenGL context.

Basic usage:

```C

    Display* disp = XOpenDisplay(NULL);

    Window win = XCreateSimpleWindow(disp, DefaultRootWindow(disp), 20, 20, 1024, 1024, 0, 0, 0);

    XMapWindow(disp, win);

    // Attempt to initialize an OpenGL 4.5 context

    if (xogl_init(disp, win, 4, 5)) {

        fprintf(stderr, "Unable initialize OpenGL!\n");

        return 1;

    }

    // OpenGL function calls

    while(1) {

        if (!running) {

            break;

        }

        // OpenGL function calls

        xogl_swapBuffers();

    }

    xogl_destroy();

```
