- Separate cairo-xlib.h Lua bindings from cairo.h
- This allows cairo.h to be used from Lua on Wayland without X11 as requirement.
- Add pango dependency for Wayland (adds pangocairo).
- Make graphics related bindings depend on BUILD_GUI.
- Remove BUILD_GUI guard around options in platform checks.
- Keeping only checks that **directly contain module requirements**
A way of creating surfaces in Lua that uses Shm allocated buffers should
be added in future. This commit only cleans up build options to avoid weird
errors.
