This reverts commit f0c503b5a9.
01:08 < Jasper> desrt, can you revert that mutter-wayland commit for me?
My laptop with git on it is out of commission.
Currently touch events are ignored in the core event handler,
and hence dealt with within GDK. If those touch events were
emulating pointer events, GDK would attempt to convert back
those events to pointer events as the frame GdkWindow doesn't
have the GDK_TOUCH_MASK set.
This results in XI_TouchBegin events being initially processed
by GDK, converted to button events, and triggering a grab op
that subverts touch events into pointer events, so the touch
is never ever seen again by GDK. This leaves GDK in an
inconsistent internal state wrt pointer grabs, so future
pointer-emulating touches will refer to the same window forever.
Fix this by handling touch events minimally, just enough to
convert XI_TouchBegin to GDK_BUTTON_PRESS within mutter, so GDK
is bypassed for every touch event just like it is for pointer
events. This, and the XIGrabDevice() that keeps coercing pointer
events when the grab operation starts, are enough to fix window
drag and drop on touch devices.

We try to exempt CSD windows from being forced fullscreen if they are
undecorated and the size of the screen; however, we also catch almost
all windows that *do* need to be forced fullscreen in this check, since
they also have decorations turned off.
Identify actual CSD windows by checking whether _GTK_FRAME_EXTENTS is set -
GTK+ will always set this on CSD windows even if they have no invisible
borders or shadows at the current time.
We explicitly turn off the legacy-fullscreen check for native wayland windows
so we don't start legacy-fullscreening them if the new
meta_window_is_client_decorated() is later made more accurate.

The user_rect represents the unconstrainted window size, and lots
of code in mutter assumes it can resize to the user_rect at any
time. If we wait for an attach to ACK and save the user rect, we'll
see lots of flickering as code is resizing to the old user_rect
at any time.
Make it a compile-time flag rather than a run-time flag, because
practically any time you're going to be debugging event spewing,
you're going to have to recompile anyway. Remove the WITH_VERBOSE_MODE
checks, too.
