c3ce738653 compositor: introduce weston_surface_geometry_dirty()
Instead of directly setting the dirty flag on weston_surface geometry,
use a function for that.

This allows us to hook into geometry dirtying in a following patch.

Also add comments to weston_surface fields, whose modification causes
transform state to become outdated.

82cb505287 tests: attach the surface's buffer when moving it
move_client() needs to attach the buffer, even if it was attached already,
because since 184df50 configure() will be called only on newly attached
surfaces, but the one that sets the test surface position is the configure
function.

184df50d3e compositor: call configure on surfaces with a null buffer too
This way the shell can know when a surface has been unmapped by
checking the value returned by weston_surface_is_mapped(surface).
The configure handlers have now width and height parameters, so
they do not need anymore to check manually the buffer size.
If a surface's buffer is NULL the width and height passed to the
configure are both 0.
Configure is now only called after an attach. The variable
weston_surface.pending.newly_attached is set to 1 on attach, and
after the configure call is reset to 0.

585c27c717 tests: make signal other than ABRT a hard failure
We handle FAIL_TEST tests by simply inverting the success flag. The
problem with this is, that if a FAIL_TEST fails by a SIGSEGV, it will be
interpreted as passed. However, no code should ever cause a SEGV, or any
other signal than ABRT. And even ABRT only in the case of an assert()
that is meant to fail. We would probably need more sophistication for the
FAIL_TEST cases.

For now, just interpret any other signal than ABRT as a hard failure,
regardless whether it is a TEST or FAIL_TEST. At least segfaults do not
cause false passes anymore.

fd51796094 tests: write logs to files
This cleans up the 'make check' output considerably. When all goes well,
you will only see the "PASS" line for each of $TESTS.

Weston logs into a separate file than stdout and stderr, so server logs
end up in one file per test, and other output to another file per test.

'make distclean' does not remove the tests/logs/ directory.

Also changes the weston-tests-env interpreter to bash, since I think &>

As for button-test, a wl_display_roundtrip is sufficient here.  The

also not needed, since the two requests will arrive at the server in
order, and will activate the surface first, then send a key event.

f63fab7241 button-test: Use wl_display_roundtrip instead of yield()
A round trip is sufficient here.  We need to make sure that the server
has received the wl_test request and that we've received the event
that the request triggers.  The wl_display_roundtrip() helper does
exactly that: it sends a wl_display.sync request, which will hit the
server after the wl_test requests and thus the wl_callback.done event
will come back after the server has seen all the previous requests and
after we've handled all preceeding event.

we deal with all wayland events before handling test protocol requests.

37816df646 Convert wl_input_device to wl_seat (and friends)
wl_input_device has been both renamed and split.  wl_seat is now a
virtual object representing a group of logically related input devices
with related focus.

It now only generates one event: to let clients know that it has new
capabilities.  It takes requests which hand back objects for the
wl_pointer, wl_keyboard and wl_touch interfaces it exposes which all
provide the old input interface, just under different names.

This commit tracks these changes in weston and the clients, as well as
similar renames (e.g. weston_input_device -> weston_seat).  Some other
changes were necessary, e.g. renaming the name for the visible mouse
sprite from 'pointer' to 'cursor' so as to not conflict.

For simplicity, every seat is always exposed with all three interfaces,
although this will change as time goes on.

notify_motion() now receives coordinates in wl_fixed_t but the test was
still passing integers.

3018b4431b tests: Add event-test, which tests for a few incoming events
We check that we get surface.enter_output and move the pointer into
the window and make sure we get input_device.pointer_enter with
the right coordinates.

There's a lot of code for a very simple test here, so we need to
figure out how to reuse most of the event handling and such.  It's also
not clear that a custom, text based protocol is practical here, we might
just use a wayland extension after all.

The idea here is to make weston load test cases as a module and then

6412718c0d Always build tests
There are no dependencies or requirements there that we don't already
need for weston itself.  So lets just always build them.

Use check_PROGRAMS for the matrix unit test case.

d1f0ab6343 compositor: simplify the matrix inversion API
The compositor will likely do an order of magnitude less matrix
inversions than point transformations with an inverse, hence we do not
really need the optimised path for single-shot invert-and-transform.

Expose only the computing of the explicit inverse matrix in the API.

However, the matrix inversion tests need access to the internal
functions. Designate a unit test build by #defining UNIT_TEST, and
export the internal functions in that case.

4520d5cafb tests: add matrix-test
Add a new directory tests/ for unit test applications. This directory
will be built only if --enable-tests is given to ./configure.

Add matrix-test application. It excercises especially the
weston_matrix_invert() and weston_matrix_inverse_transform() functions.
It has one test for correctness and precision, and other tests for
measuring the speed of various matrix operations.

For the record, the correctness test prints:

a random matrix:
   1.112418e-02   2.628150e+00   8.205844e+02  -1.147526e-04
   4.943677e-04  -1.117819e-04  -9.158849e-06   3.678122e-02
   7.915063e-03  -3.093254e-04  -4.376583e+02   3.424706e-02
  -2.504038e+02   2.481788e+03  -7.545445e+01   1.752909e-03

The matrix multiplied by its inverse, error:
   0.000000e+00  -0.000000e+00  -0.000000e+00  -0.000000e+00

   0.000000e+00   0.000000e+00   0.000000e+00   0.000000e+00
max abs error: 0, original determinant 11595.2

Running a test loop for 10 seconds...
test fail, det: -0.00464805, error sup: inf
test fail, det: -0.0424053, error sup: 1.30787e-06
test fail, det: 5.15191, error sup: 1.15956e-06
tests: 6791767 ok, 1 not invertible but ok, 3 failed.
Total: 6791771 iterations.

These results are expected with the current precision thresholds in
src/matrix.c and tests/matrix-test.c. The random number generator is
seeded with a constant, so the random numbers should be the same on
every run. Machine speed and scheduling affect how many iterations are
run.
