ENABLE_OPENGL means whether to enable the OpenGL slideshow transition
code. It does not mean whether to enable use of OpenGL in general. So
rename it to ENABLE_OPENGL_TRANSITIONS while at it.
ENABLE_HEADLESS means whether to disable use of X11 and OpenGL on X11
(and Wayland) platforms, I think, meaning Linux and maybe Solaris and
the BSDs. Maybe it should be renamed to DISABLE_X11_AND_OPENGL.
