By request on the wayland-devel mailing list, we could start collecting
useful writings here.
However, this is not meant to be a substitute to proper documentation,
though I understand it may very well become one. Better than nothing, I
guess, and hopefully helps in writing real documentation.
Feel free to add stuff.

Toytoolkit does not support setting opaqueness for anything else than
the immediate child widget of the frame widget. Backgrounds do not have
frames, so we need to poke it in manually.
This should allow Weston to paint the background without blending.

If the bind fails, do not bother pretending the EGL Wayland extension
is usable, and no need to unbind, either.
Print some important details about the GLESv2 renderer configuration
into the log.

When tiling window managers resize a non-resizable window they're violating
ICCCM. Not some hippie-community standard like EWMH, but ICCCM, which is
about as old and sacred as the constitution. If they want to force a window
to be a size it wasn't designed for, at least they could have the decency to
reparent the client window into a bigger containing window of whatever size
they think it should be. But apparently ICCCM compliance is too much to ask.
Anyway, all that just to say that it's really not our fault when we get an
enter event with coordinates outside the valid output region. But we'll
clip it anyway and work around mis-behaving tiling WMs.
Since the send-button-state request comes in on one socket and the
wayland event we're looking for comes in on another socket, the order
that we process the two in is undefined. Thus, button-test fails
intermittently, depending on which event we process first.
We change wl_display_flush() to wl_display_roundtrip(), to make sure that
we deal with all wayland events before handling test protocol requests.
Grabbed widgets should always receive motion events as if it was the
widget that would receive it if no grab was active. This means that the
focused widget should always be passed as the widget argument to widget
motion handlers.
This reverts commit 8c9c8fcf6e.

The simple clients all just call wl_display_dispatch() in a while loop
without checking the return value. Now, if the server dies or other
error occurs, we get a -1 return value instead and need to break the loop.
Do not build the tablet-shell client if --disable-tablet-shell is given.
Change --enable-tablet-shell to --disable-tablet-shell in ./configure
--help output, since it is enabled by default. Add a description.
Use proper quoting in the conditional.

since it doesn't use any of them. Fixes a build failure on systems,
where (E)GL headers are in non-standard path.

Separate simple EGL clients from other simple clients. This allows to
build either simple-shm or simple-egl, whichever you want. We avoid
linking libEGL and GLESv2 into simple-shm, and we can build simple-shm
even if nothing provides EGL, GLESv2, or wayland-egl APIs.
Change the options in configure --help from --enable to --disable, since
these are enabled by default, and you would normally only ever give the
--disable flavor. Add descriptions.
Remove the #define BUILD_SIMPLE_CLIENTS since it is not used.

configure.ac: The toytoolkit clients used to get libEGL linked to them
even if there was no cairo-egl. This is useless, and actually harmful on
platforms, where libEGL absolutely requires one of the GL ES libraries
to be linked in, too.
Look for EGL-related packages only for cairo-egl with toytoolkit.
window.c: protect all GL header includes with HAVE_CAIRO_EGL, since that
is the only case we can support EGL, GL, or GLESv2 at all. In the case
we do not have cairo-egl, add enough definitions to let us build the
stubs for EGL-related functions.
Remove some #ifdefs that were inside of the same #ifdef already.
These changes allow to build sorfware rendering toytoolkit clients
without any bits of EGL libs or headers.

Otherwise the user has no indication which package is missing for
CAIRO_EGL, and has to dig into config.log for it.

Rather than delivering touch events directly to clients, we'll now
call through the touch grab handler. The default handler (in
wayland-server) will deliver these events the same way they worked
before.

Support for zooming by using ctrl + the vertical axis (scrolling upwards
zooms in) and panning by both the horizontal and vertical axis as well
as click and drag was added to demonstrate how axis should work.

Axis events are in the same coordinate space as motion events, thus
measured in pixels. To emulate axis events for discrete events move the
axis by a number of pixels every step.

Callbacks registered via display_set_output_configure_handler() are
promised to be called when we know the current mode for the output. If
the following order of events happens:
1. toytoolkit binds to a wl_output global
2. application registers an output configure handler
3. the wl_output.mode events are received
Then in step 2 we would call the callback with uninitialised output
informations, giving it a 0x0 size.
To avoid such race, do not call the callback from
display_set_output_configure_handler() if the output has 0x0 size.
The wl_output.mode event will be received later, and that will trigger
the right call to the callback.

libwayland-server was changed to emit the new drag icon signal instead
of faking an attach event with a NULL buffer so this has to be done on
this side.
event-test assumes, that even without the very first wl_surface.attach
(and commit), the surface will have infinite (previously undef) input
region. event-test simply has test-client to create a wl_surface, and
then it forcefully sets its position and size, and assumes the input
region is now the full surface, so that notify_motion() will hit it.
Change Weston to initialize the input region to infinite, instead of
empty.

Apply wl_surface.frame request only on the next wl_surface.commit
according to the new protocol.
This makes it explicit, which repaint actually triggered the frame
callback, since commit schedules a repaint. Otherwise, something causing
a repaint before a commit could trigger the frame callback too early.
Ensure all demo clients send commit after wl_surface.frame. Note, that
GL apps rely on eglSwapBuffers() sending commit. In toytoolkit, it is
assumed that window_flush() always does a commit.
compositor-wayland assumes renderer->repaint_output does a commit.

In weston, the wl_resource:data field for a wl_surface object always
contains struct weston_surface *, never struct wl_surface *.
Even though this is just a cosmetic fix, it should reduce confusion.
