Since 16195ad the “expand” property is always set to FALSE when a
column is resized. This commit takes a different approach and enables
“expand” whenever the column is wide enough. An appropriate
“fixed-width” (so that the desired width is achieved after expanding) is
calculated using equations that are explained in the code.

Rewrites gtk_tree_view_column_request_width() and
gtk_tree_view_size_allocate_columns() to respect the minimum and natural
sizes that are already being returned by
gtk_cell_area_context_get_preferred_width().
The convoluted logic explained (not!) by this comment has been removed:
“Only update the expand value if the width of the widget has changed, or
the number of expand columns has changed, or if there are no expand
columns, or if we didn't have an size-allocation yet after the last
validated node.” This logic seems to have been a workaround for the
“jumping” behavior fixed in 16195ad and is no longer necessary.

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.

Before acting on any hint that is set by the window manager we must
first check that the hint is supported by the current window manager.
Checking that a property has a value is insufficient as it may have
been set by a previous window manager which did support the hint.

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.

With this we always roundtrip position change to the webbrowser.
This avoids conflicts when things change from both directions (app and user).
Also, we fake configure evens when there is no web client to ensure
apps get the events.
