`cargo upgrade --incompatible` in each of the nine workspaces here, then
`cargo update`. Most of it is version numbers only -- log, winit,
bytemuck, image, tokio, libc, android_logger, proc-macro2/quote, and syn
2 -> 3 with no source change. The wg-app-link submodule's twelve
dependencies were already at their latest majors, so that shared
repository needs no commit.
wgpu 28 -> 30 (and pollster 0.4 -> 1.0) is the part with API in it:
bind-group and vertex-buffer slots are optional now, `Instance::new`
takes an owned `InstanceDescriptor` carrying the platform's display
handle (the desktop passes winit's, since wgpu wants it for a GLES
surface presented on Wayland -- which is what this machine's fallback
produces; Android passes none), `RequestAdapterOptions` and
`SurfaceConfiguration` each gained a field kept at its historical value,
`get_current_texture` answers with an enum instead of a Result, and
`present` moved onto the queue.
The one that would not have failed at compile time: naga now requires
`@interpolate(flat)` on integer varyings, so `shader.wgsl`'s three u32
outputs were rejected at `create_shader_module` -- an abort on the device
rather than a build error. Flat is the only interpolation an integer can
have, so this states what the hardware already did.
Checked: build, clippy, fmt and tests in all nine workspaces (iris 196,
server 160); layer 2 screenshots on Vulkan and on force-gles, identical;
the arm64 release APK builds and the x86_64 bench ran a full
fling/stream/type/keyboard cycle on the emulator's GLES adapter.

Iris asked whether the 'unknown number of images' approach even works on
mobile. It does not, measured with a new rig (rigs/gpu-probe, no APK
needed) and sourced rather than recalled: the emulator's software Vulkan
refuses iris's descriptor-indexing request outright, and on real hardware
the current Android Vulkan Profile baseline (80.1% of active devices)
does not require VK_EXT_descriptor_indexing either -- Arm's own docs say
only Valhall/5th-Gen Mali (2019+) support it.
iris already solved the identical problem for text in I1 (the glyph
atlas). The recommendation is to generalize it to images rather than
widen the binding array further; not yet implemented, since it changes
iris's render core.
