On GTK desktops (Mint, XFCE, GNOME) Qt hands QColorDialog to GTK's
chooser. Its "Custom" row is a recent-colours list kept by GTK: every
colour picked is pushed in on the left and the oldest drops out, so a
user's saved wire colours are lost (forum topic 3190). It also ignores
the custom colours QET saves (#918) and has no swatch grid for the
double-click to accept (#1172).
Pass DontUseNativeDialog at every colour dialog, so all platforms get
the dialog Windows already shows: 16 custom slots that change only on
"Add to Custom Colors", saved across restarts.

QETElementEditor, QETDiagramEditor and QETTemplateEditor already
persist their geometry via QSettings; none of the modal QDialog
subclasses did, so any dialog resized to see more of its content
(Search and Replace, Diagram properties, Export, ...) is back to its
default size the next time it's opened.
Adds QET::trackDialogGeometry(), one call at the end of each dialog
constructor (after any default resize()), following the same
restoreGeometry()/saveGeometry() pattern as the three editors above,
stored under [dialoggeometry] and keyed by class name by default. An
explicit key is used for PropertiesEditorDialog, a single class
templated over several unrelated wrapped editors, so they don't all
fight over one saved size.
Covers the 36 dialogs of the original change (#691) plus seven added
since: RenumberElementsDialog, MaterialEntryDialog, AiAssistantDialog,
DuplicateOffsetDialog, ImageTransparentColorDialog, PdfPagesDialog and
WiringListDialog.
Deliberately not touched: BackupDialog and ImageCropDialog, which
setFixedSize() themselves, and MaterialSelectionDialog, which already
restores its own size.
A size saved while the dialog sat partly off-screen is restored on
screen: restoreGeometry() moves it back inside the available screen
(checked: saved at 1502,972 on a 1600x1000 screen, reopened at 600,317).
