Admin f03c22e47d libs: the AI stack, flowgraph, git, audio_route, win_resource and the other libraries; Flow, the asset library and VJ move to Stage
Library changes outside the platform's own dependencies (those came with the platform commits above). libs/asset and libs/flow move to the Stage repository with the apps that use them.

Covers work ebf442a94..2b1a41df4 for libs:

- wm: the Android super-app compiles tiles on the phone against the host engine
- cargo-makepad: the super-app APK is packed by `android dyn-pack`, in Rust
- cef: a page's audio can be captured instead of played
- flow: the flow-ui app and the flowgraph canvas return to the workspace, with staged progress in libs/flow
- svg: a stroke that bends tighter than its half width collapses its inner edge to the corner
- the accent a name is written with stops deciding whether search finds it
- ai stems: LaneDemixer, VocalsModel and the platform Stage origin/main needs
- The regex engine accepts \b and \B, reports the earliest match so a scan can resume after it, and can decide word boundaries on ASCII so a code sear
- workspace: Scope's settings carry the code map's tab width and the directories each prepared project hides from its map
- cef, video, platform: what Stage's browser needs from the shared layers
- platform, wm: work builds again on iOS, tvOS and wasm, and the window manager is warning-free on Windows
- ci: tools/ci, a Splash runtime that watches a branch and runs every ci.splash it finds
- stitch: the crate says what the rest of the repository says about its license
- ci: a run is one target dir and one cargo batch per target, and the wall draws
- apps: what the CI box found
- Remove Flow, asset and VJ applications moved into Stage
- tests: the workspace suite, run as a whole for the first time, passes outside the example UI tests
- libs: no warnings in the workspace check on any row
- tests: the last three failures of the CI box's night
- gif: the crate's doc examples compile
- cef: a hosted browser survives its host's exit
- tests: the three binaries over ten seconds in release come under it
- git: the memory ledger can take what it is asked for
- script: re-entrant dispatch, thread index validation, Any-based handle downcasts, UTF-8 previews; regex: never_loop fix
- fix(text): enable ttf-parser gvar-alloc for many-tuple variable fonts
- platform, widgets, wm: a touch that is taken away is cancelled, never released
- platform, wm: hosted apps ask the WM for what they cannot do themselves
- wm on Android: apps build on the phone
- task, cargo-makepad, widgets, audio: the task manager chooses its columns, graphs every process' network and disk traffic and installs itself as a D
- flowgraph: ordered ports take many wires, sockets can override their icon, and the canvas embeds as a viewport
- cef: captured frames and audio carry callback clocks and a navigation epoch
- git: timings read a portable clock
- ai: the hub's rig-fixture tests find the asset library without the asset client
- ai llm: a Metal main buffer is filled in 32 MB chunks
- diskmap: a scan lists each macOS directory in one getattrlistbulk call and classifies files without allocating or locking
- platform, widgets, audio_route, ai: window crossfades and whole-frame presents, caption controls that click, themed menus, a stereo-pair audio tap,
- builder: the Builder TUI matches the new terminal design, Windows executables carry app icons, and every app has one
- sheets, score, git, home: saves cannot cut a file short or overwrite another one, and checkouts cannot write outside the repository
- git: worktree status matches git on real repositories and can be cancelled
- cuda: builds link only the CUDA toolkit they are given, never a system install
- audio_route: one API on macOS, Windows and Linux, monitoring by default and processing only when asked, plus shaders that discard a value compile to
- platform, widgets, ai: a restyle recompiles nothing it already has, shows only complete frames, and a window can own its caption
- audio_route example: print the samples that reached the processor each second
- widgets, builder: the big widget families are features, all on by default, and the Builder takes none of them
- ai hub: a local chat with no model says so once, plainly
- ai: Claude Desktop drives any app with the F10 panel
- wm: children open no console windows on Windows
- ai: Connect hands the .mcpb to Claude Desktop itself
- civil-time: one local wall clock for every app, and it knows the zone on Windows
- ai-speech: makepad-ai-sfx (and with it ai-h3) is built only for IndexTTS
- script + wasm_bridge: no build script that reruns on every file
- build: the AI stack, csg, Scope and Source Library join the one workspace
- ai chat: the chat's backends are the CLI, MCP and cloud providers; the local model is the `localai` feature
- widgets: every widget family is a crate of its own under widgets/families, and makepad-widgets links, re-exports and registers the ones its features
- apps, examples, libs: each crate builds only the widget families it uses, and the design overlay is each app's own default feature
- livepipe: takes makepad-widgets without its default families, now that the AI stack is in the one workspace
- ai chat: a build without local AI starts on the first provider that answers here, not on "No model"
- thiserror: RUSTC_BOOTSTRAP no longer turns on the unstable generic member access API
- builder: makepad-builder.exe declares itself like a well-formed Windows program and stops a stalled build through a job object instead of taskkill
- builder + ai-cuda: the CUDA kernel progress shows in the Builder's Compile row, not scribbled over its screen
- repo: no third-party comic archive, generated models or sample asset in the tree
- builder: the Windows Builder ships as source, runs in its own console, and apps compile with Rust's GNU toolchain or Microsoft's
- win_resource: PNG decode and encode on makepad-fast-inflate instead of zune-png
- builder: one folder layout everywhere, makepad-builder.zip with only the files a Windows build reads, a Rust download over parallel connections, and

GIF en- and decoding library Build Status

GIF en- and decoder written in Rust (API Documentation).

GIF encoding and decoding library

This library provides all functions necessary to de- and encode GIF files.

High level interface

The high level interface consists of the two types Encoder and Decoder.

Decoding GIF files

// Open the file
use std::fs::File;
let input = File::open("tests/samples/sample_1.gif").unwrap();
// Configure the decoder such that it will expand the image to RGBA.
let mut options = gif::DecodeOptions::new();
options.set_color_output(gif::ColorOutput::RGBA);
// Read the file header
let mut decoder = options.read_info(input).unwrap();
while let Some(frame) = decoder.read_next_frame().unwrap() {
    // Process every frame
}

Encoding GIF files

The encoder can be used to save simple computer generated images:

use gif::{Frame, Encoder, Repeat};
use std::fs::File;
use std::borrow::Cow;

let color_map = &[0xFF, 0xFF, 0xFF, 0, 0, 0];
let (width, height) = (6, 6);
let beacon_states = [[
    0, 0, 0, 0, 0, 0,
    0, 1, 1, 0, 0, 0,
    0, 1, 1, 0, 0, 0,
    0, 0, 0, 1, 1, 0,
    0, 0, 0, 1, 1, 0,
    0, 0, 0, 0, 0, 0,
], [
    0, 0, 0, 0, 0, 0,
    0, 1, 1, 0, 0, 0,
    0, 1, 0, 0, 0, 0,
    0, 0, 0, 0, 1, 0,
    0, 0, 0, 1, 1, 0,
    0, 0, 0, 0, 0, 0,
]];
let mut image = File::create("target/beacon.gif").unwrap();
let mut encoder = Encoder::new(&mut image, width, height, color_map).unwrap();
encoder.set_repeat(Repeat::Infinite).unwrap();
for state in &beacon_states {
    let mut frame = Frame::default();
    frame.width = width;
    frame.height = height;
    frame.buffer = Cow::Borrowed(&*state);
    encoder.write_frame(&frame).unwrap();
}

Frame::from_* can be used to convert a true color image to a paletted image with a maximum of 256 colors:

use std::fs::File;

// Get pixel data from some source
let mut pixels: Vec<u8> = vec![0; 30_000];
// Create frame from data
let frame = gif::Frame::from_rgb(100, 100, &mut *pixels);
// Create encoder
let mut image = File::create("target/indexed_color.gif").unwrap();
let mut encoder = gif::Encoder::new(&mut image, frame.width, frame.height, &[]).unwrap();
// Write frame to file
encoder.write_frame(&frame).unwrap();
