Transient windows, at least not as they are today, don't exist in
xdg_shell. Subsurfaces allow for specially placed surfaces relative
to a window, so use these instead.
The input region of the cursor surface is set to empty in
pointer_cursor_surface_configure(). Since during the commit process
this function is called before the pending input region is made
current, it empties surface->pending.input instead of surface->input.
But pointer_cursor_surface_configure() is also called from
pointer_set_cursor() in order to map the cursor even if there isn't a
subsequent attach and commit to the cursor surface. In that case,
surface->input is never emptied, since the configure function emptied
only the pending input region and there wasn't a commit that made it
effective.
Fix this by emptying both pending and current input regions. The latter
shouldn't cause problems since the surface can't have a role prior to
being assigned the cursor role, so it shouldn't be mapped in the first
place.
Also change toytoolkit so that it triggers the bug.

The subsurfaces example creates a subsurface widget and uses EGL to
render to it directly rather than using the cairo context from the
widget. In theory this shouldn't cause any problems because the westoy
window code lazily creates the cairo surface when an application
creates a cairo context. However commit fdca95c7 changed the behaviour
to force the lazy creation at the beginning of each surface redraw.
This ends up making the triangle surface get two attaches – one from
Cairo and one from the direct EGL.
It looks like it would be difficult to reinstate the lazy surface
creation behaviour whilst still maintaining the error handling for
surface creation because none of the redraw handlers in the example
clients are designed to cope with that. Instead, this patch adds an
explicit option on a widget to disable creating the Cairo surface and
the subsurface example now uses that.

All the libexec programs are only built when BUILD_CLIENTS is true,
so we can just assign libexec_PROGRAMS under the condition. This lets us
drop most of the variable assignments and simplify it a bit.
https://bugs.freedesktop.org/show_bug.cgi?id=72812
Previously the option was --enable-demo-clients and the conditional was
ENABLE_DEMO_CLIENTS. They control whether or not we install the demo clients
(ie all other clients than weston-terminal and weston-info). Rename the
option and the conditional to better reflect this.
This client tests the wl_scaler and wl_surface_scaler protocol
extensions by cropping and then scaling a surface to ensure it is
rendered correctly. More details in comments in the code.
Adds a second renderer implementation to the nested compositor example
that creates a subsurface for each of the client's surfaces. The
client buffers are directly attached to the subsurface using the
EGL_WL_create_wayland_buffer_from_image extension instead of blitting
them in the redraw_handler.
The new renderer is always used if the parent compositor supports the
wl_subcompositor protocol and the EGL extension is available.
Otherwise it will fall back to the blit renderer.
Eventually the nested compositor example will want to be able to cope
with either rendering as it does now with a blit to an intermediate
surface or by attaching the client buffers directly to a subsurface
without copying. This patch moves the code that is specific to the
blitting mechanism into a separate set of functions with a vtable to
make it easier to add the second way of rendering in a later patch.
Previously the frame callback list was tracked as part of the global
compositor state. This patch moves the list to be part of the surface
state like it is in Weston. The frame callback now iterates the list
of surfaces to flush all of the callbacks. This change will be useful
when the example is converted to use subsurfaces so that it can have a
separate frame callback for the subsurface and flush the list for an
individual client surface rather than flushing globally.
The nested compositor example now responds to damage requests and
tracks them in the pending buffer state. This isn't currently used for
anything and it is immediately discarded when the surface is commited
but it will be used later when the example is converted to use
subsurfaces.
The buffer and frame callback state on the surfaces in the nested
compositor example are now double-buffered so that they only take
effect when the commit request is received. This doesn't really make
much difference for the current state that the example has but it will
be useful when more state is added in later patches.
This copies the buffer reference busy count implementation from Weston
to the nested compositor example and adds an internal nested_buffer
struct that we could eventually use to attach data. This will be
useful to adapt the example to use subsurfaces so that we can attach
our compositor-side buffer to the resource.
Otherwise if the surface is destroyed then it will crash when it later
tries to render all of the surfaces. You can replicate this by doing
killall weston-nested-client while the example is running.
The tablet-shell is unmaintained and unused. It is currently
dead-weight and a burden when we make changes to weston. Let's
drop it for now, we can pull it out of git if we find a need for it later.
It is quite possible for os_create_anonymous_file() to fail when trying
to allocate a new wl_shm buffer. Propagate this failure out from
shm_surface_prepare. Most parts of toytoolkit are already avoiding NULL
cairo surfaces.
If cairo surface allocation fails, do not try to call the widget redraw
functions, those are not prepared to deal with NULL. Also do not
schedule a frame callback, this allows us to retry drawing the next
time.
If redraw fails for the main_surface of a window, restore the widget
geometry to what the compositor currently is showing. This keeps the
window visual appearance in sync with application state, so interacting
with the application does not break too badly.
If the very first draw of any window fails, then forcefully exit the
program. E.g. if weston-desktop-shell fails to allocate buffers for the
unlock dialog, w-d-s exits, and weston unlocks the screen automatically.
This patch allows e.g. weston-terminal to stop from enlarging while
resizing, if new sized buffers can no longer the allocated. Even then,
the application stays usable, as it can often repaint in the last
successful size. It does not crash, and the user is able to resize it
smaller, too.

Data device interface in client just handle with pointer's dnd.
If a touch screen trigger dnd, it will use pointer struct like i
nput->sx, input->sy, input->pointer_focus. So if pointer is moving
when touch screen trigeer a dnd, wrong behaviore will occur.
Before touch screen start dnd, system call touch_grab()
to mark the following drag and drop operation is generated by
touch screen.
Defined some common variables in struct input to track dnd.
Note, touch screen and pointer can't generate drag and drop at the
same time, becuae data device protocol can't identify the drag
and drop event is generated by touch screen or pointer.

It seems that this was only used by the popup menu infrastructure,

showing the menu. That was broken in c680e90489, which

We don't have a reliable way to know when to clear this indicator.
Typically the pointer will still be over the window when the resize is
done and we'll get an enter event, but if the window sets a max size
the pointer may be over another window when the resize is done.
We'll need a new wl_shell (or more likely xdg_shell) event for this.
The decorations tiles start to overlap and look weird if we go below
200x200 size windows. Just set that as a minimum size if the app
doesn't provide a bigger minimum size.

This adds a hacked version of simple-shm which can create multiple
pointer and keyboard resources. The resources are created with the
command line options -p and -k. Both take an integer argument which
specifies the time in seconds after the program is started when the
resource should be created. It can also take a second time with a
colon separator to specify when the resource should be released.
For example:
weston-multi-resource -p5 -p7 -k9 -p12:14
That would create a pointer after 5 seconds, a second pointer 2
seconds later, a keyboard 2 seconds after that, a third pointer after
a further 3 seconds and finally after 2 more seconds it would release
that final pointer resource.
This can be used along with WAYLAND_DEBUG to check that it gets the
right events for example if the pointer is created while the client's
surface already has focus and so on.
Currently, the dnd sample client accepts all mime-types and assumes they
are the custom flower mime-type. Only accept if the offer has the right
mime-type.

when using cairo-glesv2 subsurface rendering code
implicitly calls eglMakeCurrent(dpy, NULL, NULL, ctx)
(since EGL_KHR_surfaceless_context is used), thus,
triangle_frame_callback:eglSwapBuffers returns EGL_BAD_SURFACE
error for all invocations other that the first one
Now that we use AC_SYS_LARGEFILE, we need to pull in config.h at least
whereever we use mmap(). Fixes at least the test-suite and simple-shm
on 32 bit systems.
Calls into cairo-gles may change the current context, so it was only by
chance that sometimes we had the proper one as current and updated the
correct texture in surface_attach().
In order to fix this, calling display_acquire_window_surface() before
binding the texture for setup is necessary. However this call has the
side effect of allocating a cairo surface for the window. At flush time,
the existence of this surface will cause an eglSwapBuffers(), even
if no rendering was done to it, leading to undefined contents on the
screen. This happens when the idle redraw task runs while there is a
pending frame callback.
Workaround this by moving the texture setup from surface_attach() to the
redraw handler, so that the cairo surface is only allocated when
redering is done.
We go one utf8 char back and then one forward. Just remember the original
position instead, which also avoids a warning about potentially
dereferencing a NULL return value from next_utf8_char().
cairo_egl_device_create(), which is called next,
already checks if EGL_KHR_surfaceless_context is
available. If not, it fallbacks to pbuffer.
