* Support both X11 and Wayland in the same build.
- Works for both Vulkan and OpenGL.
- Remove --with-wayland from genie options.
- Vulkan loads all three extensions for surface creation instead of only one.
- Add width and height parameter to GlContext::createSwapChain(), which is needed for EGL to create
a SwapChain with the given window size.
- Dirty-fix the example-22-windows to recreate the FrameBuffer by first destroying and then
recreating to make sure the window is released of its swapchain.
- Fix dbgText glitch in example-22-windows.
- Remove old X11-related dependencies for GLFW3.
* Formatting.
