Removes the hidden “resized-width” and “use-resized-width” properties
from GtkTreeViewColumn and instead uses the “fixed-width” property to
serve the same purpose. “fixed-width”, if set, will now override the
auto-sized width (-1 is now a legal value meaning “not set”).
Additional “cleanups” in this commit:
1. When the user resizes the column the “expand” property is now also
set to FALSE, in order to prevent the column from suddenly jumping to a
different width when the window is resized.
2. The code that translated mouse movement to column sizes has been
simplified:
the change in column width is now calculated directly from the distance
the mouse cursor has traveled. Weird behavior that might have happened
previously if the position of the column changed during resizing, is now
prevented.
3. There was some lengthy logic handling the keyboard shortcuts used to
resize treeview columns, which would call gtk_widget_error_bell() once
the minimum or maximum width was reached. Instead of rewriting these
checks I simply set the “fixed-width” property to what was requested,
relying on the fact that it is already clamped between the minimum and
maximum width during size allocation.
I will greatly surprised if anyone notices the missing error bell.

Splits up size_request() so that the height calculations are only done
when get_preferred_height() is called and the width calculations are
only done when get_preferred_width() is called. Since
get_preferred_width() does not change the treeview->priv->width value,
treeview->priv->prev_width will always be equal to it and can therefore
be removed. The only place where prev_width was used is a block in
gtk_tree_view_size_allocate(). This block seems to be adjusting the
horizontal scrollbar to account for treeview->priv->width having been
changed in size_request() and should no longer be necessary. A similar
block immediately above it seems to already account for the width change
in size_allocate().

After “validation” (i.e., background size calculations) of some cells,
size_request() was called here to update the internally cached size of
the treeview. Apparently not updating the sizes leads to some kind of
“inconsistency” that messes with top_row_to_dy(). In the GTK3 model for
size allocation, things are more complicated. The treeview can’t just
go ahead and calculate its own size any more; instead it reports both a
“minimum” and a “natural” size, and it doesn’t know what size it will
actually get until size_allocate(). It may be necessary to update
top_row_to_dy() to deal with not knowing the exact size.

We want to reserve space for the size of the scrollbars even when they
are not visible. And because toggling visibile to off now returns 0 for
size requests, this won't work anymore.
The window size can be queried on widget->window directly, no need to
store it in widget->allocation.
This change is necessary because gtk_widget_set_allcation() is now
checking invariants that assume it's called from insize
gtk_widget_size_allocate() and that wasn;t the case here.
Commit e32da246a8 made GtkRange's trough
respect the CSS margin property, but it also trimmed the box in which
the trough reacts to click events by the margin.
We still want to catch events in that area instead, and just make sure
the margin is applied when drawing (which was already implemented by
that commit).
This commit reverts the parts of
e32da246a8 that didn't involve drawing,
fixing the bug.

When cross-compiling, instead of depending on a natively built GTK+ (which means
building Glib, ATK, Pango, gdk-pixbuf, libX11...) for gtk-update-icon-cache,
find the host compiler and gdk-pixbuf, and build another gtk-update-icon-cache
with that.
This uses AX_PROG_CC_FOR_BUILD from autostars to find the host compiler, and
assumes that you'd set PKG_CONFIG_FOR_BUILD to a host pkg-config binary.

GtkWidget::visible is required for the widget to:
- have a preferred size other than 0/0
- have a size allocated
- return other values than { -1, -1, 1, 1 } from get_allocation()
This is an experimental patch aiming to make concepts and behaviors
inside GTK more concreate. GtkWidget::visible is now essentially what
CSS does for "display: none".
Note that if you want the effect of CSS's "visibility: hidden", you'll
have to use a GtkNotebook with an empty page as the concept of reserving
space but not drawing anything isn't supported natively in GTK.
It's a lot uglier now, but it shouldn't crash anymore.
We must update the font description for animations, but we can't free it
on query, because some paths call gtk_style_context_get_font() twice in
a row without stopping the use of the first call. So us just creating a
new font description all the time and unreffing the old one is not a
good idea. So we just mere the new one into the old one.

Previously, with STATE_FLAGS_REPLACE we would unset _all_ the state
flags on children, not just the ones that do propagate. This caused the
RTL/LTR flags to get lost.
We add a separate gtk-a11y.h single-include header for
them. This header will work much the same as gtkx.h. It
will be installed in /usr/include/gtk-3.0/gtk, but you
have to include it separately.
Since we are going to install these headers soon, we need
to make their mutual includes work in the installed location
as well. Also, avoid including individual gtk headers, to
avoid trouble with single-include guards.
This commit exposes the get_type() functions and standard
headers for accessible implementations. This makes it possible
to derive from the GTK accessible implementations without
GType magic tricks. This is necessary, because we require the
a11y type hierarchy to be parallel to the widget type hierarchy.
So, if you derive a widget and need to adjust its a11y implementation,
you have to be able to derive its accessible implementation.
This commit probably exposes more than is absolutely necessary,
it also exposes accessibles of widgets that are unlikely candidates
for deriving from.
Since not every theme renders a background for a GtkViewport (and
Adwaita master doesn't), ensure the grid+viewport we use to emulate a
text view here uses the "view" style class.
It already paints the css border, so let's make it also honor css
background. This is needed to have a box of a different color around
some widgets (e.g. latest gnome-clocks design)
If you want to get rounded corners on an hbox, instead of
:first-child {
border-top-left-radius: 5px;
border-bottom-left-radius: 5px;
}
:last-child {
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}
you now need to write:
:first-child, :last-child:dir(rtl) {
border-top-left-radius: 5px;
border-bottom-left-radius: 5px;
}
:last-child, :first-child:dir(rtl)
{
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}
