v0.2.9

Mermaid diagrams in markdown, an extended canvas format in the new bezel-canvas-core, resizable painted fences and embed cards, right-click menus, editor popups on ui::menu, nearest reveal, drag autoscroll, and hideable inactive carets.

New

• bezel-canvas-core holds the editor-free half of the canvas: the model, layouts, edits, paths and snapping, which bezel-canvas re-exports, and diagram, a read-only painter that draws a canvas at its own size. diagram::size_of gives that size.
• The canvas format adds a version, a node's Shape, an edge's route points and Stroke, and End::Circle and End::Cross. canvas_core::json_canvas::import and export translate to and from JSON Canvas 1.0; paint::color, shape, edge and end paint its parts.
• The mermaid feature of bezel-canvas-core adds mermaid::import, which lays out flowchart, state and class diagrams as a canvas.
• The mermaid feature of bezel-markdown draws ```mermaid fences as diagrams in a fence box that pans by drag and zooms from corner controls. markdown::mermaid::render draws one.
• Painted fences and embed cards drag taller from a grip along their foot in bezel-editor. The height is kept in markdown as mermaid 360 in a fence's info string and embed 360 in a link's title, and carried as Fence::height and Form::Embed(Some(_)). FenceHost::resize, Editing::sizing and BlockLayouts::painted_bounds back it.
• ui::context_menu::ContextMenu opens a menu at the pointer that holds the keyboard until it closes. Text fields and editor text open Cut, Copy, Paste and Select All on a right press, from ui::menu::edit_items and Edit; pictures in the editor open their own menu.
• menu::Item::Heading names a section over the rows after it.
• The editor's block, table, language, link and paste menus are ui::menu menus walked by the keyboard. The block menu puts quotes and callouts behind one Quote submenu.
• BlockLayouts::reveal_with takes a RevealMode: Center, as reveal does, or Nearest, the least scroll that shows the range.
• A selection or a lifted block held past the editor's scroll box scrolls it.
• ui::AppExt::set_inactive_caret makes a block caret in an inactive window outlined (InactiveCaret::Hollow, the default) or hidden (InactiveCaret::Hidden). TerminalElement::with_hollow_inactive does the same for a terminal's block cursor.
• Focused tabs, live menu rows and selected tree rows paint the glass selection.

Changed

• editor::AppExt::set_block_menu_items takes Vec<SlashItem> and block_menu_defaults returns one; BlockMenuItem is gone.
• menu::Item has a Heading variant; exhaustive matches must handle it.
• The link menu's active is a cursor: menu::Cursor, and its choice takes the chosen path and returns an Option.
• path::Ends carries from_end and to_end as End instead of from_arrow and to_arrow.
• Canvas, Node and Edge have new fields and Fence a height field; struct literals must include them.
• markdown::Form::Embed carries an optional height.
• An unfocused terminal draws no cursor, and a beam or underline cursor keeps its shape in an inactive window.

Fixed

• Tab strips no longer draw an overlay scrollbar.
• The markdown source view sets text at the body's size and leading.
