// example how to set up OpenGL core context on X11 with EGL
// and use basic functionality of OpenGL 4.5 version

// to compile on Ubuntu first install following packages: build-essential libx11-dev libgl-dev libegl-dev, then run:
// gcc x11_opengl.c -o x11_opengl -lm -lX11 -lEGL

// important extension functionality used here:
// (4.3) KHR_debug:                     https://www.khronos.org/registry/OpenGL/extensions/KHR/KHR_debug.txt
// (4.5) ARB_direct_state_access:       https://www.khronos.org/registry/OpenGL/extensions/ARB/ARB_direct_state_access.txt

Multi-dimensional array views for systems programmers

As C programmers, most of us think of pointer arithmetic for multi-dimensional arrays in a nested way:

The address for a 1-dimensional array is base + x. The address for a 2-dimensional array is base + x + y*x_size for row-major layout and base + y + x*y_size for column-major layout. The address for a 3-dimensional array is base + x + (y + z*y_size)*x_size for row-column-major layout. And so on.
