__GLFW_COCOA_GRAPHICS_SWITCHING__ specifies whether to in Automatic Graphics
Switching, i.e. to allow the system to choose the integrated GPU for the OpenGL
context and move it between GPUs if necessary or whether to force it to always
run on the discrete GPU. This only affects systems with both integrated and
discrete GPUs. This is ignored on other platforms.

Simpler programs and tools may want to enable this to save power, while games
and other applications performing advanced rendering will want to leave it
disabled.
@par
A bundled application that wishes to participate in Automatic Graphics Switching
should also declare this in its `Info.plist` by setting the
`NSSupportsAutomaticGraphicsSwitching` key to `true`.
