M3.62: thirty more generated arrowheads with rendered previews

Arrowhead gains 30 original shapes generated in code, appended after the first
ten so saved names stay stable: Barbed, Half Arrow (left/right), Concave,
Double Arrow, Chevron, Feather, Swallowtail, Reverse Triangle, Triangle to Bar,
Kite, Leaf, Drop, Half Circle, Oval, Target, Tag (+ open), Diamond (open),
Hexagon (+ open), Star, Cross, Plus, Double Bar, Dot on Bar, Slash, Double
Slash, Bracket and Fork. Each is drawn in local units of the head's weight
inside the usual 4 x 4 box, with its own stop for the stroke under it.
Arrowhead::label() names them in the menus. The Stroke panel's arrowhead
dropdowns render every head as the canvas draws it (cached textures, a shared
widgets::doc_preview that the Brushes panel now uses too) in a scrolling list.

## Arrowheads
`stroke.set {startArrow, endArrow}` takes any of 40 generated heads by name (the params doc lists them; `null` for
none): arrows (`Arrow`, `Barbed`, `Concave`, `DoubleArrow`, `HalfArrowLeft`/`Right`, `Chevron`, `Feather`,
`Swallowtail`…), filled and open shapes (`Triangle`, `Circle`, `Oval`, `Target`, `Tag`, `Diamond`, `Hexagon`, `Star`,
the `…Open` rings…) and marks (`Bar`, `DoubleBar`, `DotOnBar`, `Slash`, `DoubleSlash`, `Bracket`, `Fork`, `Cross`,
`Plus`). Each head fits a box about four times its weight (stroke weight × `arrowScale`) long and wide.
