gtk-glsl implements this via the usual -D and -U options.
Preprocessor directives aren't implemented yet, but defines are replaced
in the source code already.
This is the object that is used to create programs from. It also holds
(or will hold) all the settings necessary to parse GLSL - like defines
or include directories.
This is for operations in expressions, like and, or, shift, addition or
multiplication.
These operations need to do sophisticated type checks that can't be done
yet, so only the logical operations are implemented so far.
It's unused for now.
But the idea is that (most) nodes return a value and we can know the
type of value they return at compile-time. And then we can check type
compatibility while parsing using this function.
When a widget unparents its child widget manually in finalize, this can
lead to the parent-set signal being emitted for those child widgets. The
parent already has a ref_count of 0 though, so it can't be used in a
meaningful way. Specifically, emitting the signal will already try to
ref the parent which prints a critical.
Since GtkWidget already has a "parent" property, one can use its notify
signal instead to get notified when the parent widget changes.
... instead of returning either itself with uncomputed images or a
copy of itself with only one computed image and lots of other
uncomputed images that we're never gonna look at again.
This fixes expressions like -gtk-scaled(-gtk-recolor(...),-gtk-recolor(...))
which Adwaita uses for checkmarks and bullets.
The Vulkan renderer creates a fallback surface for each shadow
node, even if we end up not rendering anything to it. Avoiding
this is a nice optimization.
This fixes blurry text and icons whenever we apply shadows
in a hidpi window. Shadow nodes are the last ones that we
still use fallback for, and this was causing us to render
the text blurry.
Pass a scale factor when caching glyphs or looking them
up in the cache. The glyphs in the cache are rendered
with subpixel precision determined by the scale. Update
all callers to pass a scale factor according to the window
scale. This lets us render crisp glyphs on hidpi systems.
The code that checks for the proper size of the our swapchain
was not taking window scale fully into account. With this change,
setting the window scale to 2 in the inspector causes the window
to grow and rendering to be scaled up as expected, with Vulkan,
in the same way it already is with cairo.
Epoxy 1.4 has new ad hoc API that we can use to check whether GLX is
available on the current system.
If we didn't use this API, we'd have to manually dlopen libGL (or its
equivalent on different OSes) and check if it had GLX symbols; since
Epoxy already does all of this internally, we can simply ask it instead.

The GtkWidgetClass::measure vfunc is not required to assign a value to
any of the (out) parameters, so we need to initialize the locals we pass
to it, otherwise we can end up with a garbage size request.
The path bar would crash if we disposed it before all pending I/O
operations had finished. Now we remember all the outstanding
operations directly in the GtkPathBarPrivate, and deal with them
consistently.
The copy of the PangoGlyphString we do here was showing up
in some profiles. To avoid it, allocate the PangoGlyphInfo array
as part of the node itself. Update all callers to deal with
the slight api change required for this.
According to the documentation, gdk_monitor_get_geometry() reports the
monitor geometry in ”application pixels”, not in ”device pixels”,
meaning that the actual device resolution needs to be scaled down by the
scale factor of the output.
x11 backend does that downscaling, whereas Wayland backend did not,
causing a discrepancy depending on the backend used.

If the compositor prefers server-side decorations and the client doesn't
customize the title bar, we disable client-side decorations and let the
compositor know. Otherwise, we continue to use client-side decorations.

Under Wayland, an xdg_surface.configure with size 0x0 means it's up to
the client to set its size.
When transitioning from maximized state to un-maximized, the Wayland
compositor will send such an 0x0 configure so that the client can
restore its original size.
However, the original size was already constrained, so re-applying
size constrains can lead to a smaller size when using size increments.
Avoid this caveat by not applying size constrains when we are restoring
the original size.

As documented, GtkAppChooser is "typically [used] for the purpose of
opening a file". However given that applications that support neither
opening files nor URLs are filtered out, the chooser is not actual
useful for any other (atypical) usage. Change that by only applying
the filtering if a content-type was set, and use the full unfiltered
list otherwise.
