With the same case as from the previous commit, the very long "Mounted
on ..." text is now wrapped, but the text may not be left justified.
Slowly adjust the dialog width and see how the text wrapping is updated
to fit the size adjustment but the text is centred rather than left
justified.
This is because setting the halign property to Gtk::ALIGN_START does not
guarantee left alignment of text for wrapped or ellipsized Gtk::Labels.
Use the xalign property instead.
To set the xalign property there is a method in the GtkMisc (Gtk::Misc)
base class:
gtk_misc_set_alignment (Gtk::Misc::set_alignment)
However, GtkMisc (Gtk::Misc) was deprecated in Gtk 3.14 (Gtkmm 3.14)
and in Gtk 3.16 (gtkmm 3.16) set_alignment() was replaced with the
introduction of two new methods:
gtk_label_set_xalign (Gtk::Label::set_xalign)
gtk_label_set_yalign (Gtk::Label::set_yalign)
Add a check for Gtkmm method Gtk::Label::set_xalign() in configure.ac
and use it when available.

The Gdk::RGBA data type was introduced to replace Gdk::Color in
Gtkmm 3.0 [1], with Gdk::Color being deprecated in Gtkmm 3.10 [2].
With this commit we make the change to Gdk::RGBA data type which is the
modern replacement to Gdk::Color. Gdk::RGBA can be used almost as a
drop in replacement because it keeps most of the Gdk::Color interface.
Also, this commit removes the C Gtk call introduced during the
port-to-gtk3 patchset by commit:

Mostly add, but also remove, #includes so both DialogFeatures.h and .cc
include exactly the header files each needs to get the definitions they
use.
Header file #include guards are there to specifically enable this.
To better reflect that it is loading the supported actions for one file
system into the treeview, just like it's parent load_filesystems() is
initiating the loading for all the file systems.
Open the File System Support dialog, either add or remove some file
system specific commands used by GParted and press the
[Rescan For Supported Actions] button. The supported actions don't
change. However after just closing and reopening the dialog, the
supported actions do reflect the added or removed file system specific
commands.
Bisected to this commit:
4d6d464664
Display "other" in the File System Support dialog (!13)
The problem is that commit made a subset copy of the
GParted_Core::FILESYSTEMS vector, obtained from get_filesystems(), so
when the rescan ran and the FILESYSTEMS vector was updated with new
supported actions, the dialog still displayed the original subset copy,
so didn't reflect the changed supported actions.
Fix by passing a reference to the GParted_Core::FILESYSTEMS vector,
obtained from get_filesystems(), and perform the necessary filtering
inside the dialog, like before the above faulty commit. Additionally
finding and adding "other" file system to the end of the list.
Closes!38 - Fixes for minor issues with File System Support rescanning
Having a member variable named 't' which is used to share state in a
Dialog_Progress object between on_signal_show() and on_cancel() methods
is horrible. Rename to something more meaningful.
Also initialise m_curr_op in the constructor's initialisation list,
rather than later when first used in on_signal_show(). Not strictly
required, but avoids this POD (Plain Old Data) member variable being
undefined in the Dialog_Progress object between construction and when
on_signal_show() previously assigned to it for the first time and
started using it.

Writes the starting device overview information of all known devices to
the top of the saved details HTML. This is so that hopefully we don't
need to additionally ask users for their disk layouts via 'fdisk -l',
'parted print' and 'lsblk' when the saved details file is provided.
Also moves the equals separators "==================" from below to
above each operation so the each section is separated.

Some icon themes only provide large icons for stock items. This can
cause problems like overly large icons appearing in the GParted UI.
Found on Kubuntu 16.04 LTS with default breeze icon theme.
Be compatible with these icon themes by forcing scaling of stock icons
to the requested size.
Icons are used either by Gtk::Image widgets, or Gtk::CellRendererPixbuf
objects for comboboxes/treeviews. For Gtk::Image widgets we add
Utils::mk_image() that constructs Gtk::Image widgets and then sets the
pixel-size property. For Gtk::CellRendererPixbuf we add
Utils::mk_pixbuf() that first loads a Gdk::Pixbuf and then scales if
needed.
Closes#39 - After GTK3 port icons are too big on KDE
So that we might get more information from users when helping them.

It is not creating a dialog (a pop-up window managed by GParted code
itself). It is launching independent yelp program to display the help,
so remove the "_dialog" from the name to avoid any possible confusion.
In Gtk3 the progress bar height is fixed and defined by the CSS theme in
use. Changing the widget allocation size does nothing, it is always
rendered the same way.
In many themes, including Adwaita, the progressbar is very, very thin.
Provide custom CSS to specify a height of 8 pixels.
The CSS source string has to be differentiated for Gtk pre and post
3.20, because Gtk 3.20 introduced some breaking changes in the way CSS
is handled.

There is a bug affecting Gtk+ 3.22.8 to 3.22.30 in which destroying a
GtkComboBox when it is not hidden results in this message:
Gtk-CRITICAL **: gtk_widget_is_drawable: assertion 'GTK_IS_WIDGET (widget)' failed
This happens in GParted when some dialogs are closed, for example the
Create New Partition and Create Partition Table dialogs. To work around
the issue we call Gtk::Dialog::hide() in the destructors of our dialog
classes.
The issue was fixed in Gtk 3.24.0.
* Gtk 3.22.8 was released in February 2017.
* Gtk 3.24.0 was released in September 2018.

Starting from Gtkmm3 Gdk::Cursor objects cannot be constructed directly,
but instead you have to get a smart pointer to an instance by calling
the static member function Gdk::Cursor::create().
Gdk::Cursor::create() returns a Glib::RefPtr<Gdk::Cursor> object.
Gtkmm3 always uses Glib::RefPtr<Gdk::Cursor> in its interface and never
plain Gdk::Cursor.

GParted uses Gtk::Menu_Helpers::MenuList helper class to access

Create an active Linux Software RAID member which is larger than /dev
virtual file system and GParted will report the usage figure of the /dev
virtual file system for the SWRAID member.
# df -h /dev
Filesystem Size Used Avail Use% Mounted on
devtmpfs 732M 0 732M 0% /dev
# sgdisk -n 1:1M:+1G /dev/sdb
# mdadm --create --verbose /dev/md1 --level=linear --raid-devices=1 --force /dev/sdb1
mdadm: Defaulting to version 1.2 metadata
mdadm: array /dev/md1 started.
GParted reports the usage of /dev/sdb1 as:
Partition Mount Point Size Used Unused Unallocated
/dev/sdb1 /dev/md1 1.00GiB 0.00B 731.04MiB 292.96MiB
However GParted should have reported the usage as "---" for unknown
because it isn't coded to query the size of the SWRAID member within a
partition.
The fault has been bisected to this commit:
Extend un/mounting and usage reporting to unsupported file systems (!13)
95903efb1f
What happens for busy Linux Software RAID array members:
* GParted_Core::is_busy()
has custom code to identify busy members.
* GParted_Core::set_mountpoints()
has custom code to add the array device name as the "mount point" of
the member.
* GParted_Core::set_used_sectors()
falls into the else not a supported file system (because SWRAID
doesn't have a derived FileSystem implementation class).
* GParted_Core::mounted_set_used_sectors()
is called to get the file system usage of mounted, but unsupported
file systems, such as UFS and any others.
* Utils::get_mounted_filesystem_usage()
is called which queries the kernel using statvfs() and gets the file
system usage of the /dev virtual file system because the array
device name will always start /dev.
Fix by ensuring that GParted only asks the kernel for the usage of paths
which it knows are mount points of mounted file systems. (As read from
/proc/mounts and cached in the Mount_Info module). Also rename the
method, by inserting "_fs", to mounted_fs_set_used_sectors() to remind
us that it is for mounted *file systems* only.
Closes#27 - GParted may report incorrect usage for SWRAID partitions
instead of unknown

C++ initialises static member variables before main() is called.
Therefore the static members of:
struct Slots
{
static Gtk::TreeModelColumn<Glib::ustring> text;
static Gtk::TreeModelColumn<bool> sensitive;
private:
static Gtk::TreeModel::ColumnRecord record_;
};
are constructed before Gtk::Main() is called in main(). However the
Gtkmm documentation specifically says that they must be constructed
afterwards [1].
Resolve this by using the Construct On First Use Idiom [2] to delay
initialisation until the slots are first used. Normally this idiom uses
static local objects, however it is being applied to class static
objects here because the objects are accessed in many methods. The
downside of this approach is that the objects are never destructed,
which memory analysers like Valgrind could see as a memory leak, but
that is actually deliberate. That leak can be removed once we can use
C++11 and std::unique_ptr.

https://developer.gnome.org/gtkmm/2.24/classGtk_1_1TreeModelColumnRecord.html#details
"Neither TreeModel::ColumnRecord nor the TreeModelColumns contain
any real data - they merely describe what C++ type is stored in
which column of a TreeModel, and save you from having to repeat that
type information in several places.
Thus TreeModel::ColumnRecord can be made a singleton (as long as you
make sure it's instantiated after Gtk::Main), even when creating
multiple models from it.
