We need to use the allocated codepath if *any* argument is
allocated, not if one arg is not allocated.
This bug caused unnecessary calls to _gtk_bitmask_is_allocated,
as well as return completely wrong result if both bitmask are
allocated.
What is this bin doing with all these crazy deltas? Company does:
<Company> that can safely be removed
<Company> in general, code that isn't obvious can either be understood
<Company> with a bit of thinking or it can be removed
<Company> if in doubt, go for the 2nd of those :)
Most GtkBin subclasses override this strange garbage anyway, so it's
not like this code is ever *run*, per se. Just make it proxy directly
to the child, and hope nothing goes wrong.
Implement get_preferred_width, get_preferred_height, and size_allocate.
This allows GtkBin subclasses to be quick and easy, without the
author doing the subclassing to have to do much work.
If the "wider" label is the smaller one, use the wider size for both
cases. This can happen when ellipsizing a single character, which is
often smaller than the ellipsizing glpyph(s).
Functions should not have a space before the opening parenthesis. So
change output like
alpha (@color, 0.5)
to
alpha(@color, 0.5)
and do the same for "shade" and "mix".
Tests have been updated accordingly.
With ellipsizing, the ellipsized text can have a smaller height than the
non-ellipsized text. So the wider text is also higher. Example:
.<big>TEXT</big>
will ellipsize to the small text.

We must make sure to remove the weak pointer when disposing the widget
or when resetting the align widget otherwise glib will try to nullify
invalid memory.
This way we don't need a marker on GtkWidgetParivate that needs to be
unset later, so we have all our data in the same place and can avoid
problems with reentrancy and shenanigans like that.
But the main reason I wrote that is cleaner code.
With this function now available, we can do size computation in 2
ways:
(1) Compute size with size groups
(2) Compute size without size groups
And have (1) use (2) instead of setting flags on widgets. This patch
does exactly that.
With size groups now doing hfw, doing the optimization for CONSTANT_SIZE
was done too early. Size groups need to know that it's a hfw request, so
the other widgets in the size group get the correct behavior.
The label code assumed that Pango treats this as "wrap to as much space
as possible and then ellipsize all the lines", but for Pango, ellipsize
takes precedence over wrap. So do the same thing in GtkLabel.
Also updated is the reftest that checked this behavior.
We compute on-demand for size groups anyway, so we can (in theory, this
patch doesn't do that yet) get around costly cache blowing when
invalidating single widgets of a size group this way.
The current approach of using gtk_widget_get_mapped() is broken:
The usual steps taken when showing a window are:
(1) request the sizes
(2) allocate the sizes
(3) show the window in the allocated size
Showing the window with a random size between steps (1) and (2) would of
course
result in extra work and potential flickering when the widgets get
resized to
their proper sizes.
However, as GtkSizeGroup::ignore-hidden uses gtk_widget_get_mapped() to
determine visibility for a widget, the following will happen:
(1) the widget will request a 0 size
(2) the widget will be allocated a 0 size
(3) the widget will be too small when it is shown
gtk_widget_get_visible() however is set in advance. Note that toggling
visibility also causes a gtk-widget_queue_resize() call already so we
take care of changes in here automatically.
Instead of only checking the ignore_hidden flag when getting the
preferred sizes, respect it already when constructing the list of
widgets. This way, widgets don't queue resizes for groups they're
ignored in anyway.
For loops to loop over lists look nicer and actually do the right thing
with "break" and "continue" statements. So they are vastly preferred to
while loops.
This simplifies code and because sizes are cached by the widgets
themselves, it's not a large performance problem (unless people use huge
amounts of widgets in a single size group, but who does that?
The main problem is that we were emitting the row-deleted signal for the model in the middle
of the process that actually deletes the row from the model (remove the row from the array,
update the model->file_lookup hash table, etc.). In the model's caller, one of the row-deleted
callbacks was requesting an iter, which caused the model to revalidate itself - but it did
this while it was in an inconsistent state. This led to an assertion failure later when the
model resorted itself.
The fix in remove_file() is like this:
* The filteredness/visibility of the deleted node is not updated. The
node will simply be gone; we don't need to update those values at
all.
* We invalidate just the node that is being deleted.
* The model->file_lookup hash table is not completely nuked; instead,
we carefully adjust its indices.
* The row-deleted signal is only emitted at the very end, when
deletion is complete and the model is consistent.
Many thanks to William Hua for doing the detective work on this bug!

They were in the semi-public API of GtkFileSystemModel, but never actually used outside of it.
