This introduces the function widget_cairo_create().
Instead of directly referencing surface->cairo_surface, use the function
widget_cairo_create(), which will create the cairo_surface as necessary,
and just returns a Cairo drawing context. Also fix window_get_surface()
similarly.
Now we can go through idle_redraw() without always creating Cairo
surfaces and committing them. This will be useful with sub-surfaces,
where repainting one sub-surface does not need to force the repaint of
all surfaces of a window.

weston-screenshooter is a helper binary that weston launches to write the
screenshot to disk. If somebody tries to launch it by hand, print a
warning and mention the screenshot keybinding.
This way libtool will remember the libtoytoolkit LIBADD libraries.
We can drop the toolkit_libs hack and just link to libtoytoolkit.la and
libtool will add the dependencies.
All the clients here were missing the global_remove handler. Because
window.c did not have it, weston-desktop-shell and weston-keyboard
segfaulted on compositor exit, as they received some
wl_registry.global_remove events.
Add more or less stub global_remove handlers, so that clients do not
crash on such events. Toytoolkit and all applications would need a lot
more code to properly handle the global object removal.

We want to make sure that the matrix symbols are exported from weston and
that modules get them from there. To do that, we pull matrix.[ch] out of
libshared and back into weston. calibrator now also links to matrix.[ch]
and we add a IN_WESTON define to enable the WL_EXPORT macro when compiled
inside weston.
After a client has been double-buffering, and then switches to
single-buffering, it should release the 2nd buffer. That never happens
in practice here, so just add a comment and a check in case it ever
occurs in the future.
If we implemented the releasing now, it would be difficult to test.

This a basic calibration tool designed for "in factory" calibration of a touch
screen. The constants for the calibration functions:
x' = Ax + By + C and
y' = Dx + Ey + F
Are printed on stdout when the calibration is completed.
In a few cases, we set a motion handler just to be able to set a fixed
cursor. This adds a default cursor helper that can be used in those cases.
In case of the 'transformed' test case, we also avoid a brief flicker
of the pointer cursor, which is set on enter when the move grab is lifted.
Change the boolean parameter 'resize_hint' into a bitmask 'flags'.
Note, that this flags is very different to the other flags used in
creating the toysurface implementations. They do not make sense to mix
one way or the other. Prepare() cannot change the surface type, and
surface constructors do not care for dynamic hint flags.

When a window's buffer transformation is set, its buffers are
reallocated with the appropriate size (i.e., with width and height
swapped in case of 90 or 270 degree rotation).
Since the opaque region was set in frame_resize_handler(), if a client
created a frameless window setting the toplevel widget as opaque would
have no effect.
This patch fixes this by moving the call wl_surface_set_opaque_region()
to idle_resize(), and changing the latter function to set the whole
window as opaque if its toplevel widget has the opaque flag set.
To reproduce, launch the terminal, open a second window using Ctrl-Shift-N,
go back to the first window, and press Ctrl-D. The terminal's master FD gets
events even after being closed, causing terminal_destroy to be called twice
on the same object.
To fix this, I'm adding a function to stop watching an FD.
We were pulling in cairo and the image loading libraries through libshared.
Split out libshared into a core libshared and a libshared-cairo that
pulls in the extra libraries.
Listen for wl_buffer.release events in the shm path, and if a previously
posted buffer is still held by the server, allocate another one. The
maximum of two should be enough, since there is no point for a server to
hold more than one buffer at a time.
Buffer allocation happens as needed instead of window creation time.

We need more structure to the way we handle the backing storage in
toytoolkit, to make it possible to double-buffer the shm case properly.
The existing buffer handling is very complex with the three
different cases:
- EGLSurface backed Cairo surface with a window associated
- wl_shm backed Cairo surface with a window associated
- wl_shm backed Cairo surface without a window, as used by dnd.c
Introduce the toysurface abstraction, which defines the interface for
the both buffer handling cases that have a window associated. It also
means, that windows will not have a valid Cairo surface outside of their
repaint cycle.
Convert the EGLsurface case into toysurface for starters. For EGL-based
Cairo surfaces, the private data is no longer needed. Destroying
egl_window_surface will trigger the destruction of the cairo_surface_t,
not vice versa. This is possible because display_create_surface() is
shm-only.
The shm cases are left untouched.
As a side-effect, display_acquire_window_surface() and
display_release_window_surface() will no longer use the 'display'
argument. Instead, display will be the one inherited from the window.

Toytoolkit doesn't buy us anything in this case, we're not rendering or
handling regular input events. Just talk directly to wl_display and
look up the 'input_method' global directly.
The key events we pass through to the input_method_context has to have
a serial number that corresponds to the key event we got. The struct display
serial is updated on pointer enter/leave and keyboard events, but not the
input method keyboard events. So the display serial will never correspond
to the key event we're dealing with and we have to pass through the
serial we get from the key event.
This simple change allows you to drive the editor using the keyboard
(supporting backspace and delete and left and right arrow keys.) The idea
behind this change is to allow the testing of the interoperation between a

This new client, called transformed, renders a cross with the top part
red and the right green, with the same transform as the output the
surface is in.
This is based on simple-egl.
If simple-egl is toggled fullscreen, the opqaue region is set for the surface
but never removed after exiting fullscreen. This patch resets the opaque region
to 0 if the surface is not fullscreen and -o was not passed. This fixes the
problem introduced sometime since d7f282b84e, when this was last fixed.

The break statement wasn't copy and pasted along with the rest of the code
causing menu item before it ("Move to workspace below") to fall through to
the fullscreen case.
We need to clamp or center on a per axis basis. If the window is wider
but the image is taller, we need to center horizontally but
clamp vertically. We can only do that if by combining the two
functions.
The intended behavior is that a quick click (press and then release
within 500ms) just pops up the menu and doesn't select anything. Then
we can mouse around and and click to select an item. Alternatively, a
click and hold (ie press and release after 500ms) lets you press right
button, mouse down on the menu item you want and release to select it.
This is how menus work in most toolkits.
The handling in weston is fine, it's there to handle the case where
the button release happens outside any client window, since the client
doesn't get those events. If such a release happens late or we get a
second release outside the popup window we shut down the popup.
The problem is in toytoolkit, where we need to select the item if we
get a release within 500ms or if we get a second release. A second
release is the case where the first release came after 500ms and
didn't pop down the menu, and the second release event is from a click
on a menu item.

Callbacks registered via display_set_output_configure_handler() are

2. application registers an output configure handler
3. the wl_output.mode events are received

informations, giving it a 0x0 size.
To avoid such race, do not call the callback from
