The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
GTK+ paints some elements like box shadows (which Adwaita likes to (ab)use
for borders) outside the rectangle passed to gtk_render_*. This is not
an issue if our own invisible frame border is big enough, but in case
of non-resizable windows we end up clipping away part of the decoration.
Use the newly added gtk_render_background_get_clip() to make sure we
always use a mask that is large enough to contain all decorations.

GTK+ improved its CSS support, and the default theme started to make
use of it, so we must update our theming code accordingly. Add support
for margins where they make sense.
GTK+ improved its CSS support, and the default theme started to make
use of it, so we must update our theming code accordingly. Start by
supporting min-width/min-height where it makes sense.
We have been ignoring those buttons since 3.16 after they had been
broken in the default theme for a couple of versions. As nobody
appears to miss them, it's time to remove them for good.
In commit cc5def1, buttons were changed from GdkRectangles to
MetaButtonSpace units, but the corresponding memset hack was not.
This means that the clickable portion of the unshade rectangle
was always set to uninitalized memory. The effects of this were
random, but in cases where the moon is aligned just right, the
rectangle would graze over the borders, and so it would take priority
over other borders and show a pointer cursor instead of a resize
cursor.
As we opt out of GTK+/Clutter's HiDPI handling, we need to apply the
window scaling factor manually to decorations, both the geometry and
when drawing.

With support for the old metacity theme format gone, there's no
reason to keep storing theme information in terms of the old theme
properties. Just store the padding/border information for each
element directly.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
MetaFrameStyle now only holds a MetaFrameLayout, so we can cut out
the middle man and use the layout directly. And as we are already
using a single style/layout per frame set and handle frame state
and focus by setting appropriate style flags, MetaFrameStyleSet
is pointless too - just store one MetaFrameLayout per frame type
directly in the theme.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
Rest in peace you magnificent format, love-child of arcane X11 drawing
API and markup craze, you will not be missed.
We do remember however the bravery of a many men and women, who fearlessly
descended into the guts of your intrinsics and turned ugliness into beauty;
their work will still be spoken of when you will long have been forgotten.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
We now have everything in place to pick up geometry and drawing
information from GTK+ rather than the metacity theme, so do just
that; the metacity theme is now only used for some constants
(title_scale, hide_buttons, ...), which we will replace soon.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
We want to eventually pick up all theme information from GTK+ instead
of our own theme format; to prepare for this, add another helper method
to fill in geometry information from the GTK+ theme.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
GTK+ expresses the window state as style classes and widget state for
client-side decorations. Add a helper method to translate our own frame
state to the corresponding changes to the style context hierarchy.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
Sounds obvious, doesn't it?
After this change when titlebar-uses-system-font is set, the "system
font" used will not be a generic one, but match what GTK+ uses in
client-side decorations.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
In order to pick up all theme information from GTK+, a single style
context is not enough; a style hierarchy that closely matches the widget
hierarchy by GTK+'s client-side decorations will allow this soon.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
Our current use of style contexts is fairly limited - we don't
use them for much more than picking up some color information.
We will soon start to make more elaborate use of GTK style
information, but a single context will no longer be enough
to draw a frame then.
To prepare for this, add a simple ref-counted type to wrap
style information.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
Rather than defining the space to the left and right of buttons, add a
simple spacing property that defines the space between buttons, which is
what GTK+ does for client-side decorations (e.g. GtkButtons in a GtkBox).
Unfortunately the value is hardcoded in GTK+; if it is exposed in the
theme in the future, we should pick it up from there, but for now we
just use the same value as GTK+.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
From a quick code search and grep of gnome-themes-standard, none of
the themes that I inspected used this feature. Since it's the last
thing that uses a lot of old legacy GdkPixbuf code, I'd rather just
consider the feature unsupported at this point and clean up everything
I need to.
https://bugzilla.gnome.org/show_bug.cgi?id=662962
We want to synchronize the button layouts of our server side
decorations and GTK+'s client side ones. However each currently
may contain buttons not supported by the other, which makes this
unnecessarily tricky.
So add support for a new "appmenu" button in the layout, to display
the fallback app menu in the decorations.
https://bugzilla.gnome.org/show_bug.cgi?id=730752
The style context of the widget is rarely what we want. We won't
fix this to be a MetaFrames style context yet; this just changes
the internal API.
https://bugzilla.gnome.org/show_bug.cgi?id=690317
It seems that the only usage of the "widget" parameter throughout
the entire call chain was to pass between two function calls as
mutual recursion.
https://bugzilla.gnome.org/show_bug.cgi?id=671104
The theme state used to use GtkStateType, but was ported over to GtkStateFlags,
leaving behind a broken assertion that fails when using certain Metacity
themes, for example Nodoka.
https://bugzilla.gnome.org/show_bug.cgi?id=661286
If we do this, then there will be invisible borders around the top of attached
modal dialogs, which is unnecessary -- they can't be resized from the top
border and just interfere with the parent dialog.
This requires changing a bit of API to help identify the type of dialog.
https://bugzilla.gnome.org/show_bug.cgi?id=657795
There were actually *two* MetaFrameGeometry structs: one in theme-private.h,
one in frame.h. The latter public struct was populated by a mix of (void*)
casting and int pointers, usually pulling directly from the data in the private
struct.
Remove the public struct, replace it with MetaFrameBorders and scrap all
the pointer hacks to populate it, instead relying on both structs being used
in common code.
This commit should be relatively straightforward, and it should not do any
tricky logic at all, just a sophisticated find and replace.

Add an additional color type to pick up colors defined with
@define-color in the GTK+ theme's CSS:
gtk:custom(name,fallback)
(where "name" refers to the name defined in GTK+'s CSS, and fallback
refers to an alternative color spec which is used when the color
referenced by "name" is not found)
The main intent of the change is to allow designers to improve
Adwaita's dark theme variant without having to compromise on colors
which work in the light variant as well.
https://bugzilla.gnome.org/show_bug.cgi?id=648709
We now use GtkStyleContext exclusively, so it's a bit weird to store
widget state as GtkStateType and translate it always to GtkStateFlags.
Just use GtkStateFlags instead of GtkStateType.
https://bugzilla.gnome.org/show_bug.cgi?id=650586
GtkStyleContext no longer has dark/light colors GtkStyle used to
have. We already have compatibility code for them in theme.c, so
add two helper functions to make it available outside theme.c.
https://bugzilla.gnome.org/show_bug.cgi?id=650586
Rather than using a single widget's style for GTK+ colors in themes,
use the style context parameter of the drawing functions for those
colors. Right now, a single style context is shared between frames,
but this will change to support different style variants.

If mutter is going to be a "real" library, then it should install its
includes so that users can do
#include <meta/display.h>
rather than
#include <display.h>
So rename the includedir accordingly, move src/include to src/meta,
and fix up all internal references.
There were a handful of header files in src/include that were not
installed; this appears to have been part of a plan to keep core/,
ui/, and compositor/ from looking at each others' private includes,
but that wasn't really working anyway. So move all non-installed
headers back into core/ or ui/.

GtkStyle has been deprecated in favor of GtkStyleContext. A full
port would involve replacing GdkColor with GdkRGBA - leave this
out for the time being.
Bump the required version of GTK+.
