Document Info: Spot Color Objects lists colorized images and skips clear gradients

A grayscale or 1-bit image colorized with a spot color now counts as a
Spot Color Object. A gradient whose stops are all at an opacity of 0
draws nothing, so its spot stops no longer list the object.

     Document Info has a Repeat Objects category after Embedded Images. It lists each radial, grid and mirror Repeat object by name with its kind and the number of instances it makes. For a grid it gives the rows and columns instead, followed by the number of instances it draws when that is fewer. With Selection Only it lists the Repeat objects in the selection. The Document Info report and Package's report list them too (`document.info {category: "repeats"}`, `repeatObjects`).
     Document Info's Pattern Objects category lists the objects whose fill or stroke is a pattern, the category the [Document Info panel](https://helpx.adobe.com/illustrator/desktop/get-started/learn-the-basics/document-info-panel.html) page describes, each by name with the patterns it uses. With Selection Only it lists those in the selection, and the Document Info report and Package's report list them too (`document.info {category: "patterns"}`, `patternObjects`). Listing an object with a pattern fill and a pattern stroke once, listing objects inside groups and type objects whose characters use a pattern, and leaving out hidden fills and strokes, strokes with no width, guides, a compound path member's own fills and strokes, an image's fills and strokes without a shape, characters the type does not draw and patterns no art uses, and counting the listed objects in Objects, are VectorCraft's own rules. Test: `cmd::docinfo::tests::info_lists_the_pattern_objects` (vectorcraft-engine).
     Document Info's Gradient Objects category lists the objects whose fill or stroke is a gradient, the category the [Document Info panel](https://helpx.adobe.com/illustrator/desktop/get-started/learn-the-basics/document-info-panel.html) page describes as the count of objects with gradient fills or strokes. Each object is listed by name with the gradients it uses. With Selection Only it lists those in the selection, and the Document Info report and Package's report list them too (`document.info {category: "gradients"}`, `gradientObjects`). Naming a linked gradient by its swatch and any other gradient by its kind, and leaving out paint that draws nothing by the rules Pattern Objects follows, gradient swatches no art uses, gradient meshes and gradients drawn by effects, are VectorCraft's own rules. Objects counts the listed objects as Gradient Objects. Test: `cmd::docinfo::tests::info_lists_the_gradient_objects` (vectorcraft-engine).

With All Categories shown it writes every category, which is VectorCraft's own rule (`docInfo.save {category}`). Test: `panels::doc_info::tests::save_writes_the_category_the_panel_shows`.
     The Brushes panel menu's Select All Unused selects the brushes that are not used in the document, as the [Brushes](https://web.archive.org/web/20241230205225/https://helpx.adobe.com/illustrator/using/brushes.html) page (archived copy) describes. A brush counts as used when a stroke paints with it in the art (opacity masks included), in symbols, graph designs, pattern tiles or graphic styles, or in the art of a used brush (`brush.unused`).
     A rename in Brush Options and Delete Brush change every stroke that paints with the brush: in the layers and opacity masks, symbols, graph designs, pattern tiles, graphic styles and the art of other brushes. A rename gives those strokes the new name, and Delete Brush makes them plain strokes, in one undo step.
