* fix(canvas): show every top-level frame's name and select frames by it
Since clicks follow Figma's depth, the empty part of a top-level frame
that holds layers selects nothing, but a frame's name was drawn and
hit-tested only while that frame was already selected. Once a top-level
frame held layers it could not be selected from the canvas, as when one
frame is dragged into another and the outer frame is then out of reach.
Every frame on the page or in a section now shows its name, faded in
the canvas's text color and in the selection color while selected or
hovered, from the same viewport-culled label catalog as section and
component labels. Its name is a hit target whether or not the frame is
selected, so clicking it selects the frame, dragging it moves the frame,
and hovering it highlights the frame; locked frames stay out of reach.
SkiaRenderer.hitTestFrameTitle no longer takes the selected IDs.
* fix(canvas): draw and hit labels whose node is just outside the view
Label catalogs culled nodes by their own bounds, but frame, section, and
component names sit outside the node, so a node just below the view hid
a name that was on screen and could not be clicked. Label lookups now use
the viewport widened by how far labels reach. Presses and hover also test
component labels, then section titles, then frame names, the reverse of
the order they are drawn, so overlapping labels pick the one on top.
