gui_toolkit 0.3.0

Added

• Arrow-key focus navigation: once a widget that does not use arrows has the focus, the arrows move it to the
  nearest Tab stop in that direction (trapped inside modals, scrolled into view). Sliders, text fields and open
  menus keep their arrows.
• Scrollbars: every View_Scroll_Y box gets an overlay scrollbar (drag the thumb, click the track to jump);
  text_edit has vertical and horizontal bars.
• Wrapping rows: ui.flow(gap) and the Wrap box flag place children left to right and start a new line when
  the row is too narrow. Chips and the fidget button / tag / swatch rows use it.
• Corner rounding: ui.set_rounding (0 = square, 1 = default, up to 2) scales box radii and widget chrome;
  ui.rad for custom draws. Radio buttons stay round, and so do boxes with the new Fixed_Radius flag.
  Rounded rects can use squircle corners (render.set_corner_smoothing), which removes the visible kink where an
  arc meets a straight edge. At rounding 0 the Windows 11 window corners go square (platform.set_square_corners).
• Density: ui.set_density / ui.dense (Comfortable or DENSITY_COMPACT): row heights, vertical gaps and
  paddings shrink, the text keeps its size.
• Disabled and muted scopes: if ui.disabled(cond) { ... } disables everything built inside (no clicks, hover or
  focus) with a neutral look and a fade; button_icon(disabled = ...) uses it. if ui.muted() { ... } dims
  secondary content that stays interactive.
• Finishes: Palette.finish paints raised surfaces Flat, Gradient (Bootstrap 2: vertical gradient, top
  highlight, embossed text, focus glow) or Glass (Windows 7 Aero: glossy top half, bottom glow, white rim).
  ui.paint_rect gives custom draws the same finish. Palettes can also set a bar colour.
• Translucent windows: render.init(transparent = true) presents through DirectComposition with a linear fp16
  (scRGB) swap chain, so translucent pixels compose correctly; platform.set_backdrop shows the Windows 11 acrylic
  backdrop behind them.
• Selection outline: selected rows, menu items and palette entries get a crisp accent border over a light fill.
• fidget: Aero and Bootstrap themes (8 themes; Graphite is now the default), Settings for rounding, corner shape and
  density, an "Enabled" switch that disables a card, a grouped data table (collapsible department groups with
  totals, two-line headers with column totals, right-aligned numbers, column separators, alternating rows),
  --bench=N (CPU time per frame), --compact, --size=WxH, --long_text.
• tools/keyboard_test.ps1: 33 checks (arrow navigation, menus closing on a click outside).

Changed

• A box with Draw_Border keeps its border out of the layout (like CSS border-box): its children sit inside it, so a
  border never hides a child's own outline.
• Disabled boxes no longer get a dimming overlay: they switch to neutral colours and fade as a whole.

Fixed

• Context menus and dropdowns now close on a click anywhere outside, not only on clickable boxes.
• Rects ignored the alpha stack (draw.push_alpha): only text faded.
• The page and the menu bar inherited the default radius, leaving dark pixels in the window corners.
• The sort arrow and resize lines of the table header were not aligned with the column separators.

The zip holds fidget.exe (widget gallery), todo.exe, icons.ttf, LICENSE and NOTICE.md. Windows 10+ x64; the translucent Aero theme needs Windows 11 22H2+ for the acrylic backdrop.
