Revert commit 73c31ac.

That commit broke rendering on macOS. `glfwInitHint` only sets internal hints in GLFW and a subsequent call to `glfwInit` is still required. However, `glfwInitHint(GLFW_COCOA_MENUBAR, 0); glfwInit();` still results in a dock icon being created, so we are reverting that commit entirely until we figure out a way to actually disable it.

Closes #239
