Patterns: Pattern Options refuses a name another swatch has

pattern.options refused a new name that another pattern had, but not
one that a color swatch, a gradient swatch, a second swatch of the
pattern or a color group had. The rename then gave the pattern's swatch
that name, so two swatches, or a swatch and a color group, had one
name. The rename also gave the new name to every swatch that had the
old one, a color swatch included, and art linked to that color swatch
kept a link to a name no swatch had. Make and Save a Copy numbered a
pattern's or a swatch's name, but not a color group's.

pattern.options now refuses a name that a swatch or a color group has,
with "a swatch or color group named `<name>` exists". It takes a name
that only the pattern's own swatches have, such as a name Swatch
Options gave the pattern's swatch, when none of them still has the old
name. A rename gives the new name only to the pattern's swatches that
had the old one. Make and Save a Copy number a color group's name as
they number a swatch's. The new message has a row in the 17 catalogs
that translate every message (COMPLETE_MESSAGES) and in bg, da, id and
nl.

 - **Document Setup modal handoff:** Document Setup → Edit Artboards applies valid settings, closes the dialog and activates the Artboard tool. Pointer-click tests cover successful handoff, invalid settings, OK, Cancel and Undo in `dialogs/document_setup.rs`.
 - **Control bar with the Artboard tool:** while the Artboard tool is in use, the Control bar shows the active artboard's controls in place of the object controls: Preset, Portrait and Landscape, New Artboard, Delete Artboard, the Name field, Artboard Options, Rearrange All Artboards, the Transform link, Move and Scale Artwork with Artboard and, while the bar has room, the reference point with X and Y, and W and H with the Constrain Width and Height Proportions link. Each runs the command its Properties or Transform panel counterpart runs (`artboard.setProps`, `artboard.new`, `artboard.delete`, `tool.options {tool: "artboard"}`), and the reference point is the one the Transform panel uses. In an 800-point window the controls up to the Transform link fit, Move and Scale Artwork with Artboard show as their boxes alone with their names in tooltips, and the link opens the Transform panel with the artboard's position and size. Pointer and key tests in `panels/artboards.rs` cover the controls, W about the reference point, the orientation and the name.

 - **Names of new and renamed artboards, brushes and patterns:** `artboard.new` and `artboard.setProps` trim the white space around the name they are given, as the Artboards panel's rename does, and a blank name gives the artboard its default name, Artboard N for the Nth artboard. `brush.new`, `brush.duplicate`, `brush.options`, `object.pattern.make`, `object.pattern.saveCopy` and `pattern.options` trim the name as the Brush Options dialog and the Pattern Options panel do, and compare the trimmed name with the names there are; a blank name gives the name each command gives when there is none, and Brush Options and Pattern Options keep the name. Tests in `tests_panelcmds.rs`, `tests_brushsym.rs` and `tests_pattern.rs` cover each command.

+- **Pattern names and swatch names:** `pattern.options` refuses a new name that another pattern, a swatch or a color group has. It takes a name that only the pattern's own swatches have. The reference page does not say what happens when the new name is taken; the refusal follows VectorCraft's rule that swatches and color groups share one namespace (`Document::swatch_name_taken`), which `swatch.new` and `swatch.edit` also follow. A rename gives the new name only to the pattern's swatches that had the old one; any other swatch with the old name keeps it, and art linked to that swatch stays linked. `object.pattern.make` and `object.pattern.saveCopy` number a color group's name as they number a swatch's. Tests in `tests_pattern.rs` cover each command. Public reference: [Create and edit patterns](https://web.archive.org/web/20211031180358/https://helpx.adobe.com/illustrator/using/create-edit-patterns.html) (archived copy).
 - **Edit Artboards in Properties:** the active artboard's name is a field. Typing a new name and pressing Enter or clicking elsewhere renames that artboard in one undo step, as the Artboards panel's rename does (`artboard.setProps {index, name}`); pressing Escape or leaving the field empty keeps the old name. A click on the Artboard Options icon beside the field opens Artboard Options for the active artboard, as double-clicking the Artboard tool's button does (`tool.options {tool: "artboard"}`). Pointer and key tests in `panels/properties.rs` cover both. Public references: [Resize artboards](https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/add-edit-artboards/resize-artboards.html) and [Create and add new artboards](https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/add-edit-artboards/add-new-artboards.html).
 - **Artboard Escape routing:** Escape leaves Artboard editing for Selection; during a drag it first cancels the gesture. Headless egui key events cover idle Escape, active-drag cancellation and a subsequent Escape in `tests_distortkeys.rs`.
 - **Artboard deletion keys:** Delete/Backspace delete selected boards in one Undo step, retaining the original first board in the current order when all are selected, as in the public [Delete artboards guide](https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/add-edit-artboards/delete-artboards.html). The last board and active drags stay protected; neither key clears selected artwork. Headless shortcut regressions in `tests_distortkeys.rs` cover reordered boards, artwork, saved state and Undo/Redo.
