Breaking out of the layer loop left every sensor below the consuming
layer untouched, so one that was hovered stayed hovered: moving onto a
widget in a layer above never ended the hover of what it covered, and
nothing ever would.
Consumption now carries into the hit test rather than stopping the walk.
A covered widget is simply not in shape, so its hover ends and its
`HoverEnd` runs; `should_run` already refuses non-position senses once
the hover is not on, so nothing else reaches it. It is applied after a
layer rather than during one, so senses on the same layer still do not
block each other.
A wheel makes `position_only` false, so a button already hovered in a
layer above does not consume it -- but the line read as though it might.
`hovering_a_button_above_does_not_stop_a_later_scroll` is that case in the
two frames a window actually delivers it in, and the comment now leads
with it. `resting` is renamed to `position_only`, so the same word is used
throughout.
`Event::consumes` says whether having run uses up what triggered it,
defaulting to no. `run_fn` already calls `should_run` per registration,
so it ors that across everything that ran and hands it back through
`run_event`. `CursorSenses` answers it with the sense it matched: a press
or a scroll is used up, hovering is not.
That drops `TypeEventManager::registered` and the second pass over a
widget's senses -- the match that decides consumption is now the same one
that decides whether the handler runs.
A cursor that is only resting still stops at the layer it is over, which
`run_event` cannot report because nothing need answer for it to be true.
It must not stop at a widget it has merely left, though, or ending a hover
above blocks the hover below: `leaving_a_widget_does_not_block_the_layer_below`
is that case, and it fails on `main` too.
`is_momentary` becomes `position_only` on both the sense and the cursor,
inverted so it reads as what it tests.
A widget the cursor has left was being handed a blanked cursor so its
press senses would not match. `should_run` now skips non-position senses
when the pointer is not inside, which is the same rule without lying
about the input: the widget still gets the real cursor with its hover
ending.
`consumes` loses its `momentary` argument, since the cursor answers that
itself.
Replaces the taking mechanism with `CursorSenses::consumes`, which
decides only whether a layer stops the input reaching the layer below.
Nothing is removed from the cursor, and senses on one layer no longer
block each other: every sensor the pointer is inside runs.
Where the cursor rests stops at the top layer under it. Something
happening to the cursor stops only at a widget that answers to it, so a
click-only child does not swallow a scroll -- which is what `main` gets
wrong, where any hovered sensor blocks the layer below.
A widget the cursor has left still hears its hover ending, but is handed
no press or scroll: that input landed somewhere else. This is a hit test
rather than a consumption rule, and without it a press beside a button
fires the button it just left.
`a_click_and_a_scroll_in_one_frame_go_to_different_widgets` goes with the
per-kind taking it tested. Of the five that remain, two fail on `main`.
`Sized` shadowed the marker trait, so a `?Sized` bound in any crate that imports the prelude failed to resolve -- a compile error in someone else's code that nothing here would have caught. It was already biting inside iris: `default/mod.rs`, `widget/ptr.rs` and `widget/text/build.rs` all imported `std::marker::Sized` explicitly to get out from under it, which they no longer need.
`SetSize` rather than `FixedSize` because the size it sets need not be fixed -- `width(rest(2))` (a flex weight) and `width(rel(0.5))` (half the parent) build the same widget, and both are more common than `sized((100, 100))`. It also pairs with the `MaxSize` beside it in that module: one sets a length, the other caps it. The builders are unchanged.
`tests/prelude_bounds.rs` is a compile-level guard -- it fails to build if the prelude shadows `Sized` again, which I checked by reverting `src/` under it:
```
error[E0404]: expected trait, found struct `Sized`
--> tests/prelude_bounds.rs:8:22
|
8 | fn takes_unsized<T: ?Sized>(_: &T) {}
| ^^^^^ not a trait
```
The pad tab of the tabs example -- the one built out of `sized` and the flexible widths -- renders pixel-identical to before the rename.

Tests across layers, as asked, and the fifth one found a defect older than
this branch: a press fired on a widget the cursor had just left, because the
frame its hover ends is a frame it still gets dispatched on, and `should_run`
only ever looked at the cursor. A button in the corner of a list therefore
clicked when the press landed anywhere else in the row.
A widget that is not under the cursor now sees a cursor with nothing
momentary in it, which settles both halves of the question at once: it is not
its press to receive, and not its press to take from the layers below.
`CursorSense` and `CursorButton` derive `Debug`, so a failure says which
sense fired rather than `left != right`.

Reviewing this against the process we agreed: the title claimed per-kind
routing and the code decided it once for the whole frame. A scroll and a
click in the same frame both went to the button, because a widget that
matched any momentary sense consumed everything.
Consumption is now removing an input from the cursor the layers below see.
`CursorSense::take` states what each sense takes -- exhaustively, so a new
sense has to answer the question rather than inherit a default -- and
`is_momentary` is gone with the enumeration it was written on. `should_run`
and consumption share one matcher instead of two copies of the table.
Two tests, each checked to fail without the change: a click and a scroll in
one frame reach different widgets, and leaving a widget still ends its hover.
The second is a regression this review caught in its own first draft, where
the skip condition used `is_off`, which counts `End` -- the one frame a
hover-end handler has to run on.

Two majors, and the renderer is under everything else left to extract -- so it goes before the slices that would otherwise be written against wgpu 28 and then again against 30. `image` 0.25.6 -> 0.25.10 rides along. `winit` stays on 0.30.12, since 0.31 is only a prerelease and nothing here needs it; `parley` 0.11.1 is current.
What the API asked for, beyond the version:
- **An instance takes the display it will present on**, and GLES on Wayland needs it, so the window the surface is made from is handed over with it. That one matters for Android rather than for this machine.
- **`get_current_texture` returns a status rather than a `Result`**, which replaced an `unwrap` that would have panicked on a resize or an occluded window: reconfigure when the surface is outdated, lost or suboptimal, and skip the frame when there is nothing to draw into.
- **Presenting moved to the queue**, still after `pre_present_notify`.
- **Bind group and vertex buffer layouts are sparse**, so each slot states `Some(layout)`.
Verified the same way as #11: the tabs example with two runtime-added images, an image alone in a layer, and glyphs from a four-page atlas all render identically. `tests/draw_cost.rs` gives 33.6/167/587/2855 us per frame at 8/64/256/1024 layers, against 33.3/161/588/2903 on wgpu 28 -- no change.

Replaces the bindless `binding_array<texture_2d<f32>>` the renderer bound every texture through. That array needs `VK_EXT_descriptor_indexing`, which a real share of Android GPUs lack, so the old shape did not run there at all.
The two things being bound want opposite treatment, so they are now split:
- **Glyph atlas pages become layers of one `texture_2d_array`.** A glyph primitive carries a `layer` instead of a view/sampler index pair. A layer index is an ordinary sampling operand, so this needs nothing beyond plain Vulkan 1.0 / GLES. Growing the atlas recreates the array with headroom and `copy_texture_to_texture`s the old layers across, no readback.
- **A standalone image gets its own texture and its own bind group,** and draws in its own call. It no longer needs a per-instance entry in `PrimitiveData`: the bind group has already picked the texture.
`Primitives` keeps images in a list of their own as a result, with `PrimitiveChange::is_image` naming which list a renumbering belongs to -- the two have independent index spaces, so `(layer, inst_idx)` alone would collide between them.
Two notes on judgement calls, since this slice was rebuilt on top of `main` rather than transplanted:
- The source version renamed `GlyphEntry::is_colored` to `is_color` and added a second `IS_COLOR` flag constant beside the existing `GlyphEntry::IS_COLORED`. Both dropped: #10's naming and its `flags()` are kept, and UVs stay `Vec2` rather than going back to `[f32; 2]`.
- `ImageGpu` no longer holds the `Texture` behind its view, which removes an `#[allow(dead_code)]`. A `TextureView` keeps its own reference to the texture, checked by rendering rather than assumed -- see below.
### Verification
```
cargo fmt --all --check
cargo clippy --workspace --all-targets --locked -- -D warnings
cargo test --workspace --locked
```
All clean; the 4 text-edit tests pass. The only clippy output is the pre-existing future-incompatibility notice about `naga`/`wgpu`/`winit`.
Because this is a rendering change, it was also run for real rather than only compiled. The `tabs` example was rendered on this machine's GPU -- Venus onto an RX 7900 XT, confirmed from the loaded ICD (`libvulkan_virtio.so` on `/dev/dri/renderD128`) rather than assumed, since a failed Vulkan init here silently falls back to llvmpipe and would make the screenshots meaningless.
Screenshots before and after the change are **byte-identical** (same md5) in two scenes: the default tab, which exercises text (the atlas path) and rects, and the image tab with a standalone image pushed at startup, which exercises the per-image bind group. The image-tab scene needed a temporary local edit to the example to push the image without a click; that edit is not part of this branch. The same comparison, re-run after dropping the `Texture` field, is still byte-identical -- which is the check that the view alone keeps it alive.

`run_sensors` decided that a widget had consumed the frame's input from
hover alone: if the cursor was inside its shape, no lower layer saw
anything. So a button sitting over a list swallowed the list's scroll,
having registered nothing but `click()`.
Being in shape still runs a widget -- a hover highlight has to fire on the
topmost thing under the cursor regardless -- but consuming is now judged
per input kind. With nothing momentary happening the behaviour is
unchanged and the topmost widget wins the hover; with a scroll or a press
happening, only a widget that registered a matching momentary sense
consumes it.
`TypeEventManager::registered` is what makes that askable: what a widget
would match is a different question from dispatching to it, and `run_fn`
can only answer the second.
tests/pointer_routing.rs drives `run_sensors` directly, with no GPU and no
window. It fails on the unfixed code with "a scroll over the button must
still reach the list underneath it".
Replace the cosmic-text path with Parley layout and Swash rasterization, backed by shared glyph-atlas pages. Shaping, editing, rasterization, and glyph rendering move together because they share the text buffer and rendered-glyph types; splitting them further would require a temporary renderer that is immediately removed.
This is reconstructed rather than replayed from the extraction history. It also fixes issues found during review:
- texture binding changes remain set when an atlas patch follows a new page
- pressing an empty field places a caret and accepts input
- selection motion delegates collapse behavior to Parley
- character deletion follows logical clusters rather than visual neighbors
- the unused root-level Swash dependency is omitted
Four public-behavior integration tests live in `tests/text_edit.rs`: empty-field input, multibyte IME preedit replacement, UTF-8-safe backspace, and selection replacement. The old twelve-test inline block and implementation-restating cases are omitted.
Every added source comment was manually reviewed. Comments that narrated implementation or history were removed; retained comments document cache/rasterization keys, GPU upload constraints, focus representation, bidi geometry, or IME semantics.
Known limitation: atlas pages currently grow without eviction. Each page is 4 MiB on CPU and GPU. An arbitrary cap would leave cached rendered-text UVs pointing at reused glyph slots, so bounding this safely needs a later generation/invalidation change.
This changes public text types and signatures. GPU glyph rendering is covered by compilation rather than a live-surface test.
Verified with:
- `cargo fmt --all --check`
- `cargo clippy --workspace --all-targets -- -D warnings`
- `cargo test --workspace` (four integration tests pass)
Cargo still reports inherited future-incompatibility notices for existing wgpu/winit dependencies; there are no current clippy warnings.
