- the scrollbar is .ui-scrollbar with a .ui-thumb, styled by the default sheet or a theme; a press
on the thumb holds it at the point it was taken and the pointer moves it in proportion, a press on
the track jumps the thumb's middle there and holds it, and neither presses what is under the bar
(it used to centre the thumb on the pointer and press the row beneath as well);
- while a popover is up only scroll boxes inside it take the pointer, and a press outside it that
closes it forgets any press in progress;
- a transition ends exactly on its value (it stopped a rounding error short, at every frame rate).
Tests: ui_popover_mouse, ui_scrollbar, ui_ease (60/120/180/240 Hz).

A game no longer writes a host:
- The runtime reads Input itself: focus and keyboard navigation (Tab, arrows, Enter/Space,
autofocus), the pointer (hover, :active, click on release, drag), and scroll boxes with the
wheel, a draggable scrollbar, clipping and scroll-into-view.
- HTML's controls are built in (button, checkbox, radio, range, select, text, key capture), made
of plain parts a stylesheet styles, each reporting with on-change and event.value.
- ludic.ui/render3d.ludic draws with render3d's overlay: textures, named atlases (icon:NAME),
nine-slice border-image, rounded rects and rings, clipping, and a scale.
- Hooks for the program's language, sounds and clock (ui_translator, ui_sounds, ui_clock).
- ui_dev: hot reload, errors on screen, LUDIC_UI_DUMP.
- CSS:
- colours as #rgb / #rrggbbaa / rgb() / rgba() / names;
- border-radius and outline (following the radius), box-shadow, background-image and a tinted
border-image;
- group opacity, @keyframes / animation, transition;
- :focus, :focus-visible and :focus-within.
- HTML mixed content, and boolean attributes.
- render3d gains tex_width / tex_height, and the XML reader keeps text runs in order.
