In order to build the cookbook examples, we need a version of Cogl-Path
that correctly exports all its symbols; this has been fixed in Cogl only
after the 1.17.2 snapshot was made.
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.
The exported symbols regular expression in cogl-path is broken, and does
not include cogl_set_path() and cogl_get_path(), which means that we
cannot link this example. In order to distcheck Clutter, we temporarily
disable the example, with the intent of reverting this commit once Cogl
is fixed.
We don't have a tests/data directory any more since the test suites
reorganization; the cookbook examples, though, rely on the existence of
the redhand.png image. In order to fix them, we copy the file in the
examples directory, and we reference it directly. Since we need it for
the examples, and we install the example code, it's also necessary to
add the image to the EXTRA_DIST rule.
The Cogl 1.x API exports cogl_set_path() and cogl_get_path(), which
means that the regular expression needs to catch those two symbols
as well.

We need to do this for XWayland windows, since we only get the event
telling us they're an XWayland window after the compositor knows about
the window.
I know it's confusing with the triple negative, but unredirected is how
we track it elsewhere: we have an 'unredirected' flag, and 'should_unredirect'.

Ever since the change to create the output window synchronously at startup,
there hasn't been any time where somebody could set a stage region the
output window was ready, so this was effectively dead code.
We no longer unmap the toplevel windows during normal operation. The
toplevel state is tied to the window's lifetime.
Call meta_compositor_add_window / meta_compositor_remove_window instead...
Traditionally, WMs unmap windows when minimizing them, and map them
when restoring them or wanting to show them for other reasons, like
upon creation.
However, as metacity morphed into mutter, we optionally chose to keep
windows mapped for the lifetime of the window under the user option
"live-window-previews", which makes the code keep windows mapped so it
can show window preview for minimized windows in other places, like
Alt-Tab and Expose.
I removed this preference two years ago mechanically, by removing all
the if statements, but never went through and cleaned up the code so
that windows are simply mapped for the lifetime of the window -- the
"architecture" of the old code that maps and unmaps on show/hide was
still there.
Remove this now.
The one case we still need to be careful of is shaded windows, in which
we do still unmap the client window. Theoretically, we might want to
show previews of shaded windows in the overview and Alt-Tab, so we remove
the complex unmap tracking for this later.
The -L option makes curl follow redirections. This is needed for
downloading glext.h because khronos.org is using a redirect.

This adds COGL_PIXEL_FORMAT_RG_88 and COGL_TEXTURE_COMPONENTS_RG in
order to support two-component textures. The RG components for a
texture is only supported if COGL_FEATURE_ID_TEXTURE_RG is advertised.
This is only available on GL 3, GL 2 with the GL_ARB_texture_rg
extension or GLES with the GL_EXT_texture_rg extension. The RG pixel
format is always supported for images because Cogl can easily do the
conversion if an application uses this format to upload to a texture
with a different format.
If an application tries to create an RG texture when the feature isn't
supported then it will raise an error when the texture is allocated.

changed to say that it is always RGBA for textures created by the

on the pixel format used the first time data is set on the texture,
but this is only true if the data is set using a constructor.
• Added documentation for the CoglTextureComponents enum.

We need to provide an escape hatch to ClutterCanvas so that it's
possible to override the window-scaling-factor ClutterSetting. This is
going to be useful in the future in case the user has better knowledge
of the window scaling factor that is going to be used with a specific
set of ClutterCanvas contents (e.g. on different outputs or stages).
https://bugzilla.gnome.org/show_bug.cgi?id=705915
ClutterCanvas is a ClutterContent interface implementation; this means
that it can be created and modified regardless of whether it is
associated to a specific actor or a stage. For this reason, we cannot
walk the hierarchy and get the window scaling factor for high DPI
density displays out of the ClutterStage when we create the Cairo
surface that we will use to draw the canvas contents on.
We can use ClutterSettings:window-scaling-factor instead, since it's
what each ClutterStage will use anyway.
This will get slightly more complicated when we support per-output
window scaling factors (like on Wayland), but that will require changes
in the entire settings architecture anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=705915
If we get a change in the window scaling factor we want to resize the
backing store of each stage, so we use the notification on the
ClutterSettings:window-scaling-factor property to do so.
https://bugzilla.gnome.org/show_bug.cgi?id=705915
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.
