d48adf9cee gdkwindow: Remove the internal cairo_surface used for out-of-band painting
Traditionally, the way painting was done in GTK+ was with the
"expose-event" handler, where you'd use GDK methods to do drawing on
your surface. In GTK+ 2.24, we added cairo support with gdk_cairo_create,
so you could paint your graphics with cairo.

Since then, we've added client-side windows, double buffering, the paint
clock, and various other enhancements, and the modern way to do drawing
is to connect to the "draw" signal on GtkWidget, which hands you a
cairo_t. To do double-buffering, the cairo_t we hand you is actually on
a secret surface, not the actual backing store of the window, and when
the draw handler completes we blit it into the main backing store
atomically.

The code to do this is with the APIs gdk_window_begin_paint_region,
which creates the temporary surface, and gdk_window_end_paint which
blits it back into the backing store. GTK+'s implementation of the
"draw" signal uses these APIs.

We've always sort-of supported people calling gdk_cairo_create
"outside" of a begin_paint / end_paint like old times, but then you're
not getting the benefit of double-buffering, and it's harder for GDK to
optimize.

Additionally, newer backends like Mir and Wayland can't actually support
this model, since they're based on double-buffering and swapping buffers
at various points in time. If we hand you a random cairo_t, we have no
idea when is a good time to swap.

Remove support for this.

This is technically a GDK API break: a warning is added in cases where
gdk_cairo_create is called outside of a paint cycle, and the returned
surface is a dummy that won't ever be composited back onto the main
surface. Testing with complex applications like Ardour didn't produce
any warnings.

be9d1e0b3b broadway backend: allow building on OpenBSD
On OpenBSD shm_open(3) is part of libc and there is not librt, so add an

efdd68b3b0 Implement get_root_origin generically for all backends
It seems that some backends implemented get_root_origin wrong
and returned the client window coordinates, not the frame window
coordinates. Since it's possible to implement generically for all
windows, let's do that instead of having a separate impl vfunc.

ff0c470e34 broadway: remove unused libcrypt
eb1ab0dac2 removed support for authentication
based on crypt()-hashed passwords but it didn't remove the header.

Finish up with the removal.

This allows the broadway backend to build on FreeBSD (which has no
crypt.h).

unable to resize, let the core code do it, and do it properly.

4226f97d54 broadway: Support ipad on-screen keyboard
We add a custom im module for broadway that calls some broadway
specific APIs to show/hide the keyboard on focus in/out. We then forward this

the keyboard.

ddade66496 broadway: use 'click-to-focus' approach instead of 'focus-follows-mouse'
The broadway backend would move the focus from one window to another based on
where the mouse was (i.e. 'focus-follows-mouse' approach). Handling the focus
this wait didn't play well with widgets which rely on focus-in-event and
focus-out-event, like the GtkEntry when using a completion popup window, see
e.g:
  https://bugzilla.gnome.org/show_bug.cgi?id=708984

So instead, setup broadway to require a click in a window to move the focus
(i.e. 'click-to-focus' approach):

 * The implicit GDK_FOCUS_CHANGE events that were generated upon reception of
   BROADWAY_EVENT_ENTER or BROADWAY_EVENT_LEAVE are removed.

 * The broadway daemon will now keep track of which is the focused window

 * Whenever the daemon detects an incoming BROADWAY_EVENT_BUTTON_PRESS, it will
   trigger the focused window switch, which sends a new BROADWAY_EVENT_FOCUS to
   the client, specifying which windows holds the focus.

 * Upon reception of a BROADWAY_EVENT_FOCUS, the client will generate a new
   GDK_FOCUS_CHANGE.

 * gdk_broadway_window_focus() was also implemented, which now requests the
   focus to the broadway server using a new BROADWAY_REQUEST_FOCUS_WINDOW.

This is based on an initial patch from Aleksander Morgado <aleksander@lanedo.com>.

f50a3af1b7 Handle recursion from motion event handlers
If a motion event handler (or other handler running from the flush-events
phase of the frame clock) recursed the main loop then flushing wouldn't
complete until after the recursed main loop returned, and various aspects
of the state would get out of sync.

To fix this, change flushing of the event queue to simply mark events as
ready to flush, and let normal event delivery handle the rest.

5ef114ba42 Switch from sending png frames to our own encoding
This is based on the rolling hashes code from
http://cgit.freedesktop.org/~krh/weston/log/?h=remote

It works by incrementally calculating hashes for every 32x32 block
in each frame sent, and then refering back to such blocks when
encoding the next frame. This means we detect when a block matches
an existing block in the previous frame in a different position.
This is great for detecting scrolling, which we need now that
the gdk level scrolling is neutered.

We've long had double precision mouse coordinates on wayland (e.g.

position getters to use doubles and add new accessors for the
public APIs that take doubles instead of ints.
