Wireframes 2.1.0

What's new

1. Shape components draw a shape on their GameObject without code, in Edit Mode, Play Mode and builds: Add Component > Wireframes has one for every shape, such as WireframeSphere and WireframeLine.
2. Text and symbols are drawn with lines like every other shape, in 2D or 3D: CreateText and CreateSymbol create them in a container, and the WireframeText and WireframeSymbol components draw them on GameObjects.
3. The package's Default Glyphs draw the 95 printable ASCII characters with its Default Font, and 23 symbols, such as DefaultSymbols.Warning, with its Default Symbols.
4. The Glyph Editor, in Window > Wireframes > Glyph Editor, shows a glyph pack's characters and symbols in a gallery and edits each glyph's lines on a canvas or as exact X and Y values, with undo, while texts and symbols that draw with the pack follow each edit.
5. Every change to a component shows up in the next render, made in the Inspector, by undo, animation or a script, and components do no work per frame.
6. Text is aligned in its bounds, wraps at spaces or runs past them, has proportional or monospace characters with character and line spacing, and changes every frame without allocating through SetText(ReadOnlySpan<char>).
7. Glyph packs, made with Create > Wireframes > Glyph Pack, are listed in a WireframeGlyphs, where the first pack that has a glyph draws it and the Inspector says which glyphs each pack overrides; code names symbols by the enum the Glyph Editor generates for each pack, so no lookup compares strings.
8. Disabling a component or its GameObject hides its shape at no cost, and enabling it again allocates nothing.
9. Components share containers by occlusion, transparency and layer, so many of them draw in a few draw calls; a color with alpha below 1 draws transparent, and shapes draw on their GameObject's layer.
10. DrawAsGizmo draws a component's shape like a gizmo, in the Scene view and in the Game view while its Gizmos button is on, and builds leave it out.
11. Prefab Mode draws the components of the prefab being edited.
12. A character or symbol the glyphs lack is drawn as ?, with one warning for each.
13. The Shape Gallery sample names its shapes with text and has two more scenes, ComponentGallery, made of components, and TextAndSymbols, and continuous integration builds all three.
14. A container without shapes skips its work before each render once its empty chunks are released.

Known issues

1. The Hierarchy's Scene visibility toggles don't hide components' wireframes, and the Gizmos menu's per-component checkboxes don't affect gizmo shapes.
2. Clicking a component's wireframe in the Scene view doesn't select its GameObject.
3. A script that changes a GameObject's layer moves its components' shapes to that layer on their next change.
4. Text has no kerning, and the Default Font has only the printable ASCII characters.
5. Stereo rendering for XR is untested.
