compositor: rework how backgrounds are managed Background handling in GNOME is very roundabout at the moment. gnome-settings-daemon uses gnome-desktop to read the background from disk into a screen-sized pixmap. It then sets the XID of that pixmap on the _XROOTPMAP_ID root window property. mutter puts that pixmap into a texture/actor which gnome-shell then uses. Having the gnome-settings-daemon detour from disk to screen means we can't easily let the compositor handle transition effects when switching backgrounds. Also, having the background actor be per-screen instead of per-monitor means we may have oversized textures in certain multihead setups. This commit changes mutter to read backgrounds from disk itself, and it changes backgrounds to be per-monitor. This way background handling/compositing is left to the compositor. https://bugzilla.gnome.org/show_bug.cgi?id=682427

Clean up include macros mess The order and way include macros were structured was chaotic, with no real common thread between files. Try to tidy up the mess with some common scheme, to make things look less messy.

meta: Hide libmutter symbols by default and selectively export them Make meson link libmutter using -fvisibility=hidden, and introduce META_EXPORT and META_EXPORT_TEST defines to mark a symbols as visible. The TEST version is meant to be used to flag symbols that are only used internally by mutter tests, but that should not be considered public API. This allows us to be more precise in selecting what is exported and what is not, without the need of a version-script file that would be more complicated to maintain. https://gitlab.gnome.org/GNOME/mutter/merge_requests/395

Use G_DECLARE_DERIVABLE/FINAL_TYPE on some types This is only for types in the `Meta` namespace. * Clears up a lot of boilerplate * We get `g_autoptr` support for free
