workspaceAnimation: Support multiple monitors

Currently, there's one animation for the whole canvas. While it looks fine with just one screen, it causes windows to move between screens when switching workspaces. Instead, have a separate animation on each screen, and sync their progress so that at any given time the progress "fraction" is the same between all screens. Clip all animations to their screens so that the windows don't leak to other screens. If a window is placed between every screen, can end up in multiple animations, in that case each part is still animated separately. Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/1213 https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/605
workspaceAnimation: Use window clones

Alexander Mikhaylenko	b1afb946b2	workspaceAnimation: Support multiple monitors Currently, there's one animation for the whole canvas. While it looks fine with just one screen, it causes windows to move between screens when switching workspaces. Instead, have a separate animation on each screen, and sync their progress so that at any given time the progress "fraction" is the same between all screens. Clip all animations to their screens so that the windows don't leak to other screens. If a window is placed between every screen, can end up in multiple animations, in that case each part is still animated separately. Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/1213 https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/605	2020-02-26 10:36:10 +01:00
Alexander Mikhaylenko	46d5bccfc6	workspaceAnimation: Use window clones Instead of reparenting windows, clone them. This will allow to properly support multi-monitor setups in subsequent commits. Block window mapping animation while the animation is running to prevent new windows appearing during the animation from being visible at the same time as their clones. Fixes https://gitlab.gnome.org/GNOME/mutter/issues/929 https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/605	2020-02-26 10:36:10 +01:00
Alexander Mikhaylenko	f0d498062d	workspaceAnimation: Only create moving window bin when needed https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/605	2020-02-26 10:36:10 +01:00
Alexander Mikhaylenko	eeac4a3b6d	workspaceAnimation: Extract WorkspaceGroup Reimplement _syncStacking(). https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/605	2020-02-26 10:36:10 +01:00
Alexander Mikhaylenko	272cb4d523	workspaceAnimation: Extract WorkspaceAnimation Simplify the logic a bit. Introduce WorkspaceAnimation class that reparents the windows from current, surrounding and destination workspaces and manages them. Expose 'progress' property and have WorkspaceAnimationController animate it instead of animating everything separately. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/605	2020-02-26 10:36:10 +01:00

Alexander Mikhaylenko	fa31bcaa7a	workspaceAnimation: Split from WindowManager It's already too complex, and will get more complex in future, split it out. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/605	2020-02-26 10:36:10 +01:00
