We need the old rect for two purposes: to find the x/y in a resize-only
action, and to pass into the constraints code for nefarious purposes.
The constraints code takes a frame rectangle, so we convert the original
client rect into a frame rect, but never convert it back since it's
unused for the rest of the function.
Instead of playing games with the variables, just have two,
separately-scoped variables. One is the client rect, the other is the
frame rect.
For gravity-based resizing, we need to make sure that the requested
rectangle has the proper x/y position given by the gravity resize,
rather than the bogus root_x_nw / root_y_nw parameter.
Make the test for this more explicit.
With our surface_mapped strategy, implement_showing might not
change whether the window has been shown or not, and thus we
might end up clearing pending_compositor_effect before the window
is mapped.
Only clear pending_compositor_effect when the effect has actually
been used.
Remove extend_by_frame and unextend_by_frame. Use a dumb hack in
window.c to translate into window geometry in back. We'll soon track
all rectangles in MetaWindow in terms of the window geometry.
It's been long enough. We can mandate support for these, at least
at build-time. The code doesn't actually compile without either
of these, so just consider that unsupported.
The Alt+F7 and Alt+F8 keybinds for moving and resizing windows allow you
to move and resize the window off the screen, so allow the same for the
menu items as well, since they're marked with the same accelerator.

If we start a grab op from a keybind / menu, we'll handle the
ButtonPress and drop the grab then, never giving the window a chance
to handle what it needs to do before the grab is dropped.
This means that if you use Alt+F7 to move a window around, move it
to a side-tiling or maximization area, and then left-click, it will
just hang there in the sky.
The entire point of it was to check whether the window was on the
right screen. Since we don't handle multiple screens anymore, we
don't need to check anything anymore.
We track changes to windows fullscreen state and stacking order
to determine a monitor's in-fullscreen state, but missed the
obvious case of moving a fullscreen window between monitors.

dx/dy should be against the regular window's rect, and need to
be ignored when we're resizing. Instead, we use gravity to anchor
the window's new rectangle when resizing.
Our focus stealing prevention is still mostly inherited from metacity;
in particular, a (non-transient) window that is not on the current
workspace will not be given focus. This behavior made sense in the
GNOME 2 days, where workspaces were separated much more strictly.
However this is no longer the case in GNOME 3 - activating a launcher
will switch workspaces if necessary, and so will the app switcher.
There is no good reason to not do the same for other user actions
like clicking a URL or activating a search result, so allow activation
of windows on non-active workspaces if a proper timestamp is supplied,
assuming that this is a strong enough indication that we are dealing
with a legitimate user action.

Effectively we have been accepting CurrentTime timestamps for years,
but still complained about "stupid pagers" when encountering them;
just accept that we will never limit treating 0 timestamps as current
time to pagers.

Except while reading _NET_WM_WINDOW_OPACITY, opacity is between 0 and 255. With
guint8, we'll get compiler warnings if arbitrary int values are passed.
