A docked ScriptUI panel only ever saw its preferredSize: the host drew
it in a scroll area at max(dock, preferred) and the script's window never
learned the dock. scriptui.resize now gives a window a size: the script's
window takes it, lays itself out again and runs onResizing / onResize.
The dock host sends it whenever the panel's dock size changes, so
window.size is the dock's, as in After Effects.

Add Per-Corner Roundness to Rectangle Path: a checkbox (off by default) and four Pixels properties (top-left, top-right, bottom-right, bottom-left). New rectangles initialise the four values from their Roundness, so ticking the box keeps the shape; the radii are animatable and expression-driven.\n\nrect_radii() builds the path clockwise from the top-left with kappa quarter-circle arcs. Overlapping radii scale down like CSS border-radius; negative and non-finite radii are square; rect() delegates to it, so uniform roundness clamps to half the shorter side as before.\n\nLottie rc has one r: four equal static radii export as that value; mixed or animated radii export roundness 0 with a warning. Import puts r into the four per-corner values so ticking the box on an imported rectangle keeps the shape.\n\nTests: path geometry and clamping, rendered per-corner pixels, Lottie equal/mixed/checkbox-off export.
A drag that started on a script control stopped at the window edge:
moves outside were dropped and a release outside never reached the
control. While a button is held, the control it was pressed on now gets
the moves (with screen and control-relative coordinates) and the
release, wherever the pointer is, as in After Effects. Every MouseEvent
also carries buttons (held: 1 left, 2 right, 4 middle), so a handler can
tell a drag from a hover; scriptui.mouse accepts it too.

The renderer applies every ancestor's transform, so a scaled null above a
camera already carries the camera's children. A Scale key with one shared
ease gets a separate Z ease before its speed is scaled.
Position speeds stretch with the path's direction at each key and Scale's Z
speed with the factor, so the ease keeps its shape. A 3D layer under a 2D
parent scales its own Z only when no 3D ancestor's Scale already carries it.
A 2D parent's Scale carries no depth, so its 3D children scale their own Z.
Percentage guides keep their percent exactly instead of drifting by rounding.
Tests now check the specific errors and cover a layer parented to a camera.
Like After Effects' File > Scripts > Scale Composition.jsx: a factor, or a new
width or height that keeps the aspect ratio, in one undo step. Layers whose
parent has a Scale follow that parent; nested precomps and expressions are
left as they are. No dialog yet.
