GCC by default allows pointer arithmetic on void* pointers and treats
them as having a size of 1 byte. This is non-standard behaviour and
causes errors on some compilers so we should try to avoid
it. -Wpointer-arith warns about these cases.
We use the micro version for distinguishing released tarballs and Git
builds; the maintainer compiler flags should be enabled for the latter,
and not just for unstable cycles, since it makes sense to have extra
warning flags even on stable cycles.
We also want to allow people to turn on -Werror on demand, so let's add
a third option to --enable-maintainer-flags.
Since we have a decent XI1 and XI2 implementation, now, we should turn
the support for XInput on by default.
The actual implementation to be used at run-time is still left to be
decided by the user.
This is a lump commit that is fairly difficult to break down without
either breaking bisecting or breaking the test cases.
The new design for handling X11 event translation works this way:
- ClutterBackend::translate_event() has been added as the central
point used by a ClutterBackend implementation to translate a
native event into a ClutterEvent;
- ClutterEventTranslator is a private interface that should be
implemented by backend-specific objects, like stage
implementations and ClutterDeviceManager sub-classes, and
allows dealing with class-specific event translation;
- ClutterStageX11 implements EventTranslator, and deals with the
stage-relative X11 events coming from the X11 event source;
- ClutterStageGLX overrides EventTranslator, in order to
deal with the INTEL_GLX_swap_event extension, and it chains up
to the X11 default implementation;
- ClutterDeviceManagerX11 has been split into two separate classes,
one that deals with core and (optionally) XI1 events, and the
other that deals with XI2 events; the selection is done at run-time,
since the core+XI1 and XI2 mechanisms are mutually exclusive.
All the other backends we officially support still use their own
custom event source and translation function, but the end goal is to
migrate them to the translate_event() virtual function, and have the
event source be a shared part of Clutter core.
Clutter has some platform-specific API that is accessible only if the
right backend has been compiled in. Third party applications that wish
to be portable across backends might want to use defines and other
pre-processor tricks to determine header inclusion and API usage.
While Clutter has an internal set of symbols it can use, third party
applications don't have the luxury of being able to access the config.h
generated by Clutter's configure script.
For this reason, Clutter should install a configuration header with a
series of namespaced defines that can be picked up by applications and
other third party code.
The ffs function is defined in C99 so if we want to use it in Cogl we
need to provide a fallback for MSVC. This adds a configure check for
the function and then a fallback using a while loop if it is not
available.

Keeping the Cogl 2.0 API reference in the build is getting far more
troublesome than it's worth.
It's breaking distcheck far too often, and it makes it impossible to
rebuild the build environment from tarballs - which is something that
some distributions (namely: the Debian-based ones, but not limited to
them) do in order to change build scripts using their own rules.
The check-news option in configure.ac conflicts with the idea of using a
buildbot to do a distcheck.
Since we're doing some validation on the state of the build during the
release-check phase we should add the NEWS file check there.

Not tested (but checked that it compiles).
There's no reason to only enable the check for the cex100. Hopefully
should work.
We make sure not to enable both the evdev and the tslib backend at the
same time as the DeviceManager is a singleton and we can't have both
subclasses at the same time for now.
This backend is a event backend that can be enabled for EGL (for now).
It uses udev (gudev) to query input devices on a linux system, listens to
keyboard events from input devices and xkbcommon to translate raw key
codes into key keysyms.
This commit only supports key events, more to follow.
Building the API reference for Cogl 2.0 is fairly confusing: the API
itself is experimental and for internal use only -- though we want
feedback for it.
Let's build the API reference only when Clutter is configured with a
specific configure switch, so that people that wish to give feedback on
the API and its documentation can do it.
So we can keep track of the experimental progress of Cogl 2.0 features
this adds a standalone Cogl 2.0 Reference Manual which doesn't cover
the deprecated 1.x symbols and removes the need for a "Cogl
experimental API" chapter since those sections now make up the main
table of contents.
By defining COGL_ENABLE_EXPERIMENTAL_2_0_API in config.h we can ensure
that all internal clutter and cogl code can use the Cogl 2.0 API and by
not using AM_CPPFLAGS we avoid having other tools such as glib-mkenums
and the gir-scanner from inadvertently using the define also.
The profiling support was broken - probably during the restructuring of
the build environment, but I'm too lazy to bisect that.
The fix is trivial, and everything works as it should.
Previously in the tests/tools directory we build a disable-npots
library which was used as an LD_PRELOAD to trick Cogl in to thinking
there is no NPOT texture extension. This is a little awkward to use so
it seems much simpler to just define a COGL_DEBUG option to disable
npot textures.
CLUTTER_EGL_BACKEND is used to define a special EGL native backend to
use and was introduced for the CEX100 EGL backend. Unfortunately
CLUTTER_EGL_BACKEND was defined to "cex100" for eglnative, which is
obviously wrong.
The paches defines the right values for CLUTTER_EGL_BACKEND for the
eglnative and cex100 flavours.
Don't generate both bz2 and gz tarballs: we only use the former anyway,
and the latter just adds time for distcheck to complete.
The gz tarball will be generated by the remote installation scripts when
publishing the release.
