The :unscaled-font-dpi property is used to override the existing
:font-dpi value when running on high DPI density displays; since it's a
write-only property we don't need to have a separate storage, nor we
need to choose between :font-dpi and :unscaled-font-dpi depending on
whether or not either has been set. If we select which one to use
between :font-dpi and :unscaled-font-dpi when computing the font
resolution, we end up breaking the code that relies on changing
:font-dpi directly on a per-Settings basis.
Like we do for the windowing surfaces, we should have a run time knob
(in the form of an environment variable) to allow changing the scaling
factor of the font resolution.
We want the settings object to handle setting and getting the
window scaling factor value, both through backend-specific settings and
through the CLUTTER_SCALE environment variable. This means turning the
ClutterSettings:window-scaling-factor property into a readwrite one,
instead of write-only, so that ClutterStage implementations will be able
to query the window scaling factor on construction.

If anything in the system changes the config for fontconfig then an
XSetting will be set to record the last timestamp of the config file.
This is presumably so that applications can be notified that it has
changed and can reload the configuration. However once this setting is
set it will remain set for the lifetime of the X server. This causes
Clutter to handle the setting during the initialisation of the
backend. Previously this would cause problems because Clutter would
end up creating the default PangoFontMap before the backend has
created the CoglContext. The PangoFontMap would in turn cause the
default CoglContext to be created. Clutter will then later create its
own CoglContext which means there will be two and the first one will
be leaked. Cogl currently can't really cope with multiple contexts
being created so it falls apart.
This patch fixes it to skip reloading the config for fontconfig if
there isn't a default font map yet. The config will presumably
naturally be read with the latest values when it is finally created
anyway so it doesn't need to be read immediately.

On top of the existing "Settings" group in the settings.ini file we
should have two more groups:
Environment - contains all the configuration possible through
environment variables
Debug - contains all the possible debug variables
ClutterSettings should be able to load its initial state by using
configuration files in SYSCONFDIR and XDG_CONFIG_HOME. This allows
Clutter to have a system (and user) configuration on platforms that
do not have XSETTINGS bridges.
Add a setting that controls whether ClutterText actors in password mode
should display the last input character for a defined time. This helps
on touch-based interfaces.

The :fontconfig-timestamp is a write-only property that will get updated
by the underlying platform whenever the fontconfig configuration has
been changed — i.e. when the fontconfig caches should be rebuilt after
the user has installed a new font.
A property to control the minimum time that has to elapse before a press
is recognized as a long press. This will be used by ClutterClickAction,
but it can be shared across touch-based gestures.
This adds a wrapper macro to clutter-private that will use
g_object_notify_by_pspec if it's compiled against a version of GLib
that is sufficiently new. Otherwise it will notify by the property
name as before by extracting the name from the pspec. The objects can
then store a static array of GParamSpecs and notify using those as
suggested in the documentation for g_object_notify_by_pspec.
Note that the name of the variable used for storing the array of
GParamSpecs is obj_props instead of properties as used in the
documentation because some places in Clutter uses 'properties' as the
name of a local variable.
Mose of the classes in Clutter have been converted using the script in
the bug report. Some classes have not been modified even though the
script picked them up as described here:
json-generator:
We probably don't want to modify the internal copy of JSON
behaviour-depth:
rectangle:
score:
stage-manager:
These aren't using the separate GParamSpec* variable style.
blur-effect:
win32/device-manager:
Don't actually define any properties even though it has the enum.
box-layout:
flow-layout:
Have some per-child properties that don't work automatically with
the script.
clutter-model:
The script gets confused with ClutterModelIter
stage:
Script gets confused because PROP_USER_RESIZE doesn't match
"user-resizable"
test-layout:
Don't really want to modify the tests
