When building with --enable-profile we now depend on the uprof-0.3
developer release which brings a few improvements:
» It lets us "fix" how we initialize uprof so that instead of using a shared
object constructor/destructor (which was a hack used when first adding
uprof support to Clutter) we can now initialize as part of clutter's
normal initialization code. As a side note though, I found that the way
Clutter initializes has some quite serious problems whenever it
involves GOptionGroups. It is not able to guarantee the initialization
of dependencies like uprof and Cogl. For this reason we still use the
contructor/destructor approach to initialize uprof in Cogl.
» uprof-0.3 provides a better API for adding custom columns when reporting
timer and counter statistics which lets us remove quite a lot of manual
report generation code in clutter-profile.c.
» uprof-0.3 provides a shared context for tracking mainloop timer
statistics. This means any mainloop based library following the same
"Mainloop" timer naming convention can use the shared context and no
matter who ends up owning the final mainloop the statistics will always
be in the same place. This allows profiling of Clutter with an
external mainloop such as with the Mutter compositor.
» uprof-0.3 can export statistics over dbus and comes with an ncurses
based ui to vizualize timer and counter stats live.
The latest version of uprof can be cloned from:
git://github.com/rib/UProf.git
Let's try to keep Cogl's build as non-recursive as possible, in the hope
that one day we'll be able to make it fully non-recursive along with the
rest of Clutter.
This requires some autotools magic when setting up the environment
through autogen.sh, because autoreconf does not do the right thing
by default.
The correct order for setting up localization is:
‣ autopoint
‣ aclocal
‣ ...
otherwise aclocal will copy the system's gettext.m4 instead of honouring
the version we specified with AM_GNU_GETTEXT_VERSION in configure.ac.
Some debugging tools might require full visibility for the Clutter
symbols; for this reason, and to match what the Clutter dependencies
already allow, we should provide a configure switch to disable linking
with the -Bsymbolic flag.

* Use new introspection --include-uninstalled API since we don't want
to try to find the clutter-1.0.pc file before it's installed.
* Use --pkg-export for Clutter-1.0.gir, since we want the .gir file to
contain the associated pkg-config file.
* Drop the use of --pkg for dependencies; those come from the associated
.gir files. (Actually, --pkg is almost never needed)
* Add --quiet

Intel CE3100 and CE4100 have several planes (framebuffers) and a
hardware blender to blend the planes togeteher to produce the final
image.
clutter_cex100_set_plane() lets you configure which framebuffer clutter
will use for its rendering.
Intel CE3100 and CE4100 SoCs are designed for TVs. They have separate
framebuffers that are blended together by a piece of hardware to make
the final output. The library that allows you to initialize and
configure those planes is called GDL. A EGL GDL winsys can then be
use with those planes as NativeWindowType to select which plane to use.
This patch adds a new ClutterBackendCex100 backend that can be
selected at compile time with the new --with-flavour=cex100 option.
--quiet has been added to g-ir-scanner in the 0.9.1 cycle. We really
want to be able to compile clutter with 0.6.14 to be able to reuse
gir files that are distributed in current distributions.
Use the INTROSPECTION_SCANNER_ARGS (previously unused) variable to
convey --quiet when necessary.

DRM is available on more platforms than Linux (e.g. kFreeBSD), but
Clutter currently FTBFS there because of not being an alternative to
the __linux__ code (where it should be HAVE_DRM).
Instead of copying the DRM data structures, we should use libdrm when
falling back to directly requesting to wait for the vblank.

In 7fae8ac051 the two cogl-defines.h files from GLES and GL were
unified. However this missed out the COGL_HAS_GLES[12] defines from
GLES. The configure.ac still made an AC_SUBST for the right version
but the replacement was never put in any headers. This fixes it so
that instead of directly calling AC_SUBST the value is now put into a
variable which later gets added to COGL_DEFINES so that it will end up
in cogl-defines.h
There was an initializer for the COGL_DEFINES variable which sets it
to the empty value before it is filled in. The name of the variable
wasn't spelt right so it wouldn't work properly. This doesn't really
matter because it would default to empty anyway.
The cookbook should also include fully functional code examples. We can
even XInclude them into the docbook XML itself.
The examples should be built with the coobook, so that we can always
make sure they are up to date.
The P_() macro adds a context for the property nick and blurb. In order
to make xgettext recognize it, we need to drop glib-gettexize inside the
autogen.sh script and ship a modified Makefile.in.in with Clutter.
The AS_ALL_LINGUAS m4 macro allows configure-time generation of the
ALL_LINGUAS variable from the translations inside po/ instead of using
the LINGUAS file.

Under big GL, glext.h is included automatically by gl.h. However under
GLES this doesn't appear to happen so it has to be included explicitly
to get the defines for extensions. This patch changes the
clutter_gl_header to be called cogl_gl_headers and it can now take a
space seperated list of multiple headers. This is then later converted
to a list of #include lines which ends up cogl-defines.h. The gles2
and gles1 backends now add their respective ext header to this list.

We now always aim to use pkg-config based configuration when possible,
but when not configure.ac now knows the difference between GLES_CM
libraries that contain EGL symbols (I.e. a separate EGL library doesn't
need to be found) and GLESv1_CM libraries that don't contain EGL
symbols.

I was fed up to cd into the tests/conform or tests/interactive directories
to launch a specific test. Now, with the power the abs_ variants of
builddir and srcdir we can run specific test from any directory.

The Clutter Accessibility Library is an implementation of the ATK,
the Accessibility Toolkit, which exposes Clutter actors to accessibility
tools. This allows not only writing accessible user interfaces, but also
allows testing and verification frameworks based on A11Y technologies to
inspect and test a Clutter scene graph.

This copies the files for the GLU tesselator from Mesa. The Mesa code
is based on the original SGI code and is released under a BSD license.
The memalloc.h header has been replaced with one that forces the code
to use g_malloc and friends. The rest of the files are not altered
from the original so it should be possible to later upgrade the files
by simply overwriting them.
There is a tesselator.h header which is expected to be included by
rest of Cogl to use the tesselator. This contains a trimmed down
version of glu.h that only includes parts that pertain to the
tesselator. There is also a stub glu.h in the GL directory which is
just provided so that the tesselator code can include <GL/gl.h>
without depending on the system header. It just redirects to
tesselator.h
The -Bsymbolic-functions linker flag allows to avoid intra-library
PLT jumps on ELF platforms. It is similar to the aliasing hack in
GLib and GTK+, but definitely less messy.
The configure script should look for the flags, in order to support
platforms/linkers that do not have it.
This will be defined in cogl-defines.h whenever Cogl is built using a
winsys that supports X11. This implies CoglTexturePixmapX11 will be
available.
To make this work the two separate cogl-defines.h.in files have been
merged into one. The configure script now makes a @COGL_DEFINES@
substitution variable which contains the #define lines to put in
rather than directly having them in the seperate files.
When configuring the glx flavour we were always explicitly adding -lGL
to the linker flags even when a pkg-config file was found which should
take care of that option for us.
When building for gles1/2 we now always try and look for a libglesv1_cm
or libglesv2 .pc file with details about where to find the library and
headers.
This adds an automake USE_TSLIB condition to decide when we should
compile clutter-event-tslib.c. This is in preparation for consolidating
the eglx and eglnative backends.
With this patch if you ./configure clutter using
--with-flavour=opengl-egl-xlib then it will use EGL + OpenGL instead of
the default GLX and OpenGL.
These days upstream driver work is more focused on improving EGL than it
is GLX so likewise we want to make sure Clutter has good support for
EGL.
This adds a separate variable name "CLUTTER_SONAME_INFIX" to define the
infix for the clutter library that gets linked. Currently the WINSYS
corresponds to the directory we enter when building to compile the
window system and input support, but it is desirable to be able to
define multiple flavours that use the same WINSYS but should result in
different library names.
For example we are planning to combine the eglx and eglnative window
systems into one "egl" winsys but we will need to preserve the current
library names for the eglx and eglnative flavours.
