Exporting the same folio to DXF twice gave files with the same entities
in a different order, so two exports never compared equal and a DXF could
not be diffed to spot a change. The export walked diagram->items(), whose
order follows memory addresses; saving had the same fault until
bugtracker #343.
Items are now taken in stacking order (z, then insertion order, which a
load makes the file's order), from the same rect query Diagram::toXml()
uses. Anything the query misses keeps its items() place after the rest.
Checked in the Export dialog on grafcet.qet, three folios, two exports
per build: master's differ every time, these are byte-identical, and both
contain exactly the same entities, only reordered.

DiagramImageItem::toXml() PNG-encoded every picture on every save,
autosave and copy, whether or not it had changed. That is most of the
cost of pictures in a project: resaving one holding 60 of them took
6.2 s and now takes 3.8 s.
The PNG bytes are now kept and reused while QPixmap::cacheKey() still
matches, so any edit (replace, crop, mirror, transparency) re-encodes
without each of those functions having to invalidate anything. On load
the cache is filled with the file's own bytes, so the first save
encodes nothing either.
Output is byte-identical to before on the example projects. A picture
whose PNG came from another encoder now keeps its original bytes
instead of being re-encoded; the pixels are identical.

A picture can now carry a caption, set from its properties panel
("Libellé"). It is drawn centred under the picture at the folio's
normal text size whatever the picture's scale, turns with it, and
moves, copies and prints with it because the picture itself paints it.
Clicking the caption selects the picture.
Saved as a "label" attribute on <image>, written only when non-empty:
a project without labels saves byte-for-byte as before, and older
versions open a labelled project and simply ignore the caption.

A file written before drawn items carried a uuid gets them from the folio
uuid, the kind of item and its order in the file. Three integration tests
pin what that promises: opening the same file twice gives the same uuids,
the first save writes exactly those and a reopen keeps them, and a uuid
repeated in a hand-edited file ends up naming one item only.
Each fails when the derived uuid is replaced by a random one. They read
drawing_item_view unsorted, which is what found the first-row-only bug
in QETSql::execReadOnly() fixed by the previous commit.

Since #1046, QETSql::execReadOnly() runs a query with PRAGMA query_only
set and switches it off before returning. Switching it off aborts a
statement SQLite is still stepping through ("abort due to ROLLBACK"), and
QSQLITE has already stepped to the first row by then. A query that
produces its rows as it goes -- a UNION ALL without ORDER BY -- therefore
came back with its first row only and no error. A sorted query was not
affected, because SQLite has read every row before returning the first.
Every query from the SQL box of a table, a saved <graphics_table> query
and the scripting qet.query() goes through here.
The checked run is now finished before query_only is switched off, and a
query that passed is run again for the caller. SQLite refuses a write at
its first step, so passing that step is what proves a statement reads
only; the second run is of a statement already shown to be read-only.

- qet_edit: every op taking a text, shape or image "index" also takes its
uuid, resolved at run time with textIndex()/shapeIndex()/imageIndex().
Those are only required when a uuid is used.
- qet_element_build writes a uuid on every part (the caller's, or a new
one) and returns them in part_uuids; qet_element_info lists part and
terminal uuids.
- README and tests: drawing_item_view, uuid addressing, part uuids.

Lines, rectangles, ellipses, arcs, polygons, PLC tables and static texts
now save a uuid, as terminals and dynamic texts already did, so a tool can
name one part of a symbol. The graphic parts keep it next to their styles,
since all of them save through stylesToXml(); a part read from a
definition that predates this gets one on the next save.
Paste renews them, as it already did for terminals -- and now for dynamic
texts too, which were pasted with their source's uuid. A placed element
gives its dynamic texts fresh uuids anyway, so only the definition's own
identity changes. PartTerminal::uuid() returns the terminal's saved uuid
rather than inheriting the graphic-part one it never writes.

Now that they carry a uuid, the folio's drawing furniture gets rows of its
own: shape, independent_text and image, plus drawing_item_view, which finds
any of them by uuid without knowing its kind first and says which folio it
is on.
Rows follow edits, not just loads. The script API's query() and every
other reader go through newQuery() without a rebuild, so an item's row is
queued on each change (moves, restyles, text edits, uuid renewal) and the
queue is flushed by newQuery() and updateDB() -- a queued write is a set
insertion, which matters for a drag that moves hundreds of items per mouse
step.
A pasted copy joins its folio still carrying its source's uuid and is only
renewed afterwards, so a flush in between must not let the copy overwrite
its source's row. Each row remembers the item that wrote it; another item
with the same uuid waits until uuidChanged() says it has its own.

The constructor built QRegularExpression("[^A-Z]") on every call, and
compiling it cost more than the rest of Diagram::convertPosition() put
together -- about 95k instructions a call under callgrind. Every element
row of the project database pays it on each rebuild, as does anything
else that turns a scene point into a folio cell.

Elements, conductors, terminals and tables already carry a uuid. The
drawing furniture beside them did not, so a script or the MCP server could
only name a line, a box or a note by its index in a position-sorted list,
which shifts whenever one is added or removed.
- QetShapeItem, IndependentTextItem and DiagramImageItem get uuid(),
newUuid() and setUuid(), read from and written to a "uuid" attribute.
- A folio loaded from a file written before this (or carrying a duplicate
uuid) derives one from the folio uuid, the item kind and its order in the
file, so the same file gives the same uuids on every load and a re-save
is stable -- the #754 lesson for conductors.
- Paste and folio duplication renew them, as they already do for elements
and conductors.
- Scripting: texts(), shapes() and images() end each line with the uuid;
textIndex(), shapeIndex() and imageIndex() turn one back into an index.
- misc/qet-mcp: qet_diff keys texts, shapes and images on uuid when both
sides have one, so a move or edit reads as a change to that item.

Showing a selected conductor's properties in the selection-properties
dock is now a preference, on the General page under Appearance:
"Afficher les propriétés d'un conducteur sélectionné dans le panneau
Propriétés de la sélection". It is off by default, so selecting a
conductor does what it did before unless the user turns it on.
This replaces the View-menu toggle, which defaulted to on; that entry
is dropped in the merge with master. Same setting key
(diagrameditor/conductor_properties_panel).

After customising, the bar now opens at the cursor like every other
time, instead of where the customising window was.
A size grip in the bar's corner sets its width. The tiles are laid out
in rows that wrap at that width, so a bar with many commands and pinned
elements becomes a block rather than one long strip; the height follows
the rows, and the width is saved. Until the user sets one, the tiles
stay on one row, as before. The grip is driven by hand: QSizeGrip asks
the window manager to resize, and on X11 a popup is not managed, so
nothing would happen. The hint line wraps rather than being cut off at
narrow widths.
The customising window remembers the size it was left at.

The bar's customising window gets an element search next to the command
list. Type part of a name, then drag a hit onto the bar, double-click
it, or press Enter to pin the best one. A pinned element shows as its
icon among the commands, and clicking it places the element, as the
picker does.
Pinned elements are saved in the same list as the commands, by
collection path (common://, custom://, company://), so the row keeps
the user's order. Elements embedded in a project are not offered: their
path names the project as loaded now. Elements are offered for the
empty-folio bar only; with something selected the bar is for acting on
it. Once any element is pinned there, the palette folder grid under the
bar is hidden, and comes back while typing a search.
Dragging a pinned element off the bar onto the commands, or a double
click, removes it. The Preferences page shows pinned elements by name
and icon, and removing one there drops it instead of listing it as a
command. The customising window is now kept on screen, since it is
taller than before.

While a collection search is active the tree is replaced by the flat
ranked list, and that list had no drag support: dragging a result only
moved the selection. Anyone used to searching and then dragging lost the
drag as soon as they typed.
The tree's drag is moved into a static ElementsTreeView::execElementDrag()
taking the source widget, and the results list uses it from the path each
row already carries, so the drag content and pixmap are the same.

Holding Ctrl+Shift over a folio pans it, and only a key release seen by
the view ends that. A Ctrl+Shift shortcut that opens a window -- the
command search, Ctrl+Shift+M -- takes the keyboard before Ctrl and Shift
are released, so the view never sees the release. On Windows, where the
Shift press itself already reports Ctrl+Shift, the folio then stayed in
pan mode after a command was chosen: a hand cursor, and clicks ignored,
so a drawing tool picked from the search did nothing. On Linux the Enter
key's release happened to reach the view and end it.
The view now remembers that it pans because of Ctrl+Shift (not because
the hand tool was chosen) and stops when it loses the focus, or at a
click made without Ctrl+Shift, instead of waiting for a release it may
never get.
Reproduced on Linux by holding back Enter's release, as Windows does:
the line drawn after "Ctrl+Shift+M, une ligne, Enter" is not saved on
master and is with this change. Ctrl+Shift+drag and the hand tool still
pan (a dragged step does not move), as on master.

Most commands on the empty-folio ring start a drawing tool, and the view
left the right button alone while a tool ran, so the gesture after one
that started a tool only cancelled the tool: every other gesture opened
the context menu instead of the ring.
Now a right drag always shows the ring. A running tool is ended when the
drag starts, as picking another tool from the toolbar would. A plain
right click still goes to the tool, which cancels or finishes it as
before.
