If no POT file is found, gettext will automatically create it; this, in
turn, will cause msgmerge to be run, and that will cause the PO files to
be touched and changed at the very first call for `make`.
Having the PO files with unstaged changes will ultimately lead to merge
issues will pulling from the remote repository between releases - unless
`git checkout -f` is called prior to `git pull -r`.
I think intltool only has some rule to avoid that from happening unless
on dist, but I have no intention of dragging intltool into the build of
a library that barely has localized messages.

docs: Remove checks for whether an effect is disabled
docs: Add recipe about implementing a ClutterEffect
docs: Add example of setting background color with ClutterEffect
docs: Add example of a border added through ClutterEffect
clutter_clone_get_paint_volume was being exported from the shared
library because the function wasn't declared static. This function
shouldn't be exposed because it should be accessed through
clutter_actor_get_paint_volume.
pre_paint() and post_paint() implementations don't need
to check whether an effect is disabled: Clutter will
not apply an effect unless it is enabled.
So remove code which checks whether the effect is
enabled or disabled from the example applications and the
documentation.
Add a recipe showing how to implement two simple
effects, based on ClutterEffect: an always gray background,
and a border with configurable width and color.
Also explains the necessity to queue a redraw on
the associated actor if the effect's properties change,
and shows how to implement that.
The example gives the GObject code for both effects,
as well as an example application showing how to use them.
The example also demonstrates how to disable/enable an effect,
making the border round an actor togglable.
Add example of a simple background color effect applied via
pre_paint() implementation in a ClutterEffect subclass.
This is a simple effect with an incomplete GObject
implementation (no properties, setters or getters)
to make it as easy to follow as possible.
The texture containing the image for the redirected actor will always
be painted at a 1:1 texel:pixel ratio so there's no need to use linear
filtering. This should also counteract some of the effects of rounding
errors when calculating the geometry for the quad.
On a Fedora system (and maybe others) there is a wrapper script called
i686-pc-mingw32-pkg-config. This script unsets the PKG_CONFIG_PATH
variable and then sets the PKG_CONFIG_LIBDIR variable so that it won't
pick up the native system .pc files. This breaks cross compiling in
mingw-fetch-dependencies.sh because it ends up removing its attempts
to set a local search path.
To fix this, the mingw-fetch-dependencies script now generates its own
wrapper script which instead sets PKG_CONFIG_LIBDIR to the local
clutter-cross prefix and then runs the original pkg-config program
from the search path. This should have the same benefit of preventing
it from finding native system .pc files on systems that don't provide
a cross pkg-config. The cross compiling for json-glib and the
recommend args to pass to configure when building clutter are updated
to set the PKG_CONFIG varible to point to this wrapper script.
Since there is very little now left in the env.sh file generated by
mingw-fetch-dependencies.sh it can be removed. What remained (The
CFLAGS="-mms-bitfields" and PKG_CONFIG_PATH=$ROOT_DIR/lib/pkgconfig) can
simply be passed explicitly when calling ./configure.
This removes the use of -mno-cygwin from our generated env.sh for cross
compiling with mingw.
I don't know that anyone is building clutter under cygwin, and our
BuildingClutterOnWindows wiki page only describes building with msys not
cygwin so I think its fair to assume that this build configuration is
untested and thus not supported by us currently. Since the -mno-cygwin
option is deprecated it could well be that there is a better
cross-compilation solution available for cygwin these days if you want
to build programs that don't depend on cygwin libraries.
This remove CXXFLAGS since we don't have any c++ code in Clutter and
also removes the redundant -L$ROOT_DIR/lib from LDFLAGS and
-I$ROOT_DIR/include from CPPFLAGS and CFLAGS. (These should get added by
pkg-config)
This adds some blurb at the end the mingw-fetch-dependencies.sh script
that gives an example of how to go on and build clutter after fetching
all dependencies.
Since Tor does not currently provide win32 binaries for json-glib we
need to cross compile it before we can build clutter. This extends
mingw-fetch-dependencies.sh so it can fetch, unpack and cross-compile
json-glib into the same prefix as the binary dependencies.
It shouldn't be necessary to explicitly override CC,CPP,AR,NM,LD etc in
the env.sh helper script that mingw-fetch-dependencies.sh generates.
Clutter's ./configure script should figure all of those out for us.
This removes the "Do you want to checkout and build Clutter?" option
from the mingw-cross-compile.sh script and renames the script
mingw-fetch-dependencies.sh
As it stands the mingw-cross-compile.sh script isn't enough to fetch all
the dependencies for building clutter, since Tor doesn't provide binaries
for json-glib so the option to checkout and build clutter can't work.
Also it doesn't seem ideal to clone a fresh clutter repo instead of
being able to compile the source of the current repo.
if cross compiling clutter using mingw using an out of tree build
directory then a pre-requisite for creating the resources.o file
containing the transparent cursor is for the win32 directory itself to
be created at $(top_builddir)/clutter/win32.
glib already has a data type to manage a list of callbacks called a
GHookList so we might as well use it instead of maintaining Cogl's own
type. The glib version may be slightly more efficient because it
avoids using a GList and instead encodes the prev and next pointers
directly in the GHook structure. It also has more features than
CoglCallbackList.
Previously we were applying the culling optimization to any actor
painted without considering that we may be painting to an offscreen
framebuffer where the stage clip isn't applicable.
For now we simply expose a getter for the current draw framebuffer
and we can assume that a return value of NULL corresponds to the
stage.
Note: This will need to be updated as stages start to be backed by real
CoglFramebuffer objects and so we won't get NULL in those cases.
To give quick visibility to the things going on relating to clipping and
culling this adds some more CLIPPING debug notes to clutter-actor.c and
clutter-stage.c
As documented in cogl-pipeline-private.h, there is a precedence to the
ClutterPaintVolume bitfields that should be considered whenever we
implement code that manipulates PaintVolumes...
Firstly if ->is_empty == TRUE then the values for ->is_complete and
->is_2d are undefined, so we should typically check ->is_empty as the
first priority.
This fixes a bug in _clutter_paint_volume_cull() whereby we were
checking pv->is_complete before checking pv->is_empty which was
resulting in assertions for actors with no size.
Drawing and clipping to paths is generally quite expensive because the
geometry has to be tessellated into triangles in a single VBO which
breaks up the journal batching. If we can detect when the path
contains just a single rectangle then we can instead divert to calling
cogl_rectangle which will take advantage of the journal, or by pushing
a rectangle clip which usually ends up just using the scissor.
This patch adds a boolean to each path to mark when it is a
rectangle. It gets cleared whenever a node is added or gets set to
TRUE whenever cogl2_path_rectangle is called. This doesn't try to
catch cases where a rectangle is composed by cogl_path_line_to and
cogl_path_move_to commands.
ClutterDragAction should be able to use the newly added ClutterSettings
property exposing the system's drag threshold.
Currently, the x-drag-threshold and the y-drag-threshold properties (and
relative accessors) use an unsigned integer for their values; we should
be able to safely expand the range to include -1 as the minimum value,
and use this new value to tell the ClutterDragAction that it should query
the ClutterSettings object for the drag threshold.
The storage of the properties has been changed, albeit in a compatible
way, as GObject installs a uint ↔ int transformation function for GValue
automatically.
The setter for the drag thresholds has been changes to use a signed
integer, but the getter has been updated to always Do The Right Thing™:
it never returns -1 but, instead, will return the valid drag threshold,
either from the value set or from the Settings singleton.
This change is ABI compatible.

ClutterState is missing some documentation on how to define transitions
using ClutterScript definitions; it is also missing some example code
for both the C API and the ClutterScript syntax.
The allocation of the ClutterBox is not enough to be used as the paint
volume, because children might decide to paint outside that area.
Instead, we should use the allocation if the Box has a background color
and then do what Group does, and union all the paint volumes of the
children.

In 9ff04e8a99 the builtin uniforms were moved to the common shader
boilerplate. However the common boilerplate is positioned before the
default precision specifier on GLES2 so it would fail to compile
because the uniforms end up with no precision in the fragment
shader. This patch just moves the precision specifier to above the
common boilerplate.
The CLUTTER_ENTER and CLUTTER_LEAVE event types were mistakenly ignored
by clutter_event_get_device(), when returning the device from a
non-allocated ClutterEvent.
