Nico Weber e735ee5251 Tests/LibGfx: Add YCCK jpeg test files 
Obtained by running:

    convert rgb_components.jpg -colorspace cmyk \
        -sampling-factor 1 ycck-1111.jpg
    convert rgb_components.jpg -colorspace cmyk \
        -sampling-factor 2 ycck-2111.jpg
    convert rgb_components.jpg -colorspace cmyk ycck-2112.jpg

where rgb_components.jpg is the file in Tests/LibGfx/test-inputs/jpg.

(I used the web version of `convert` at
https://cancerberosgx.github.io/magic/playground/index.html)

While this does indeed produce a cmyk jpg (using the YCCK encoding
internally), it uses the mathematical rgb->cmyk conversion and does
not embed an cmyk color space in the output jpg.

Normally, cmyk images are for printing and hence converting them
from cmyk to rgb using a color profile like SWOP leads to better
results. So if a cmyk image does not contain color space information,
applications might use something like SWOP instead of the simple
math transform to convert to RGB. Programs doing that will show
these images as fairly muted (and would arguably be correct doing
so).

Hence, tests using these images shouldn't check their RGB values.
Ideally, we'd add a way to get the raw cmyk data from a cmyk jpeg,
and then tests could test color values against that.

The -1111 image uses no subsampling, meaning each channel's sampling
factor is 1.

The -2111 image uses subsampling for the non-Y channels, meaning the
sampling factors are 2 for Y and 1 each for YYK.

The -2112 image uses subsampling for the two C channels, meaning the
sampling factors are 2 for Y and K and 1 each for YY.

We correctly render the -1111 variant (using e.g.
`Build/lagom/bin/image -o out.png .../ycck-1111.jpg).

We render the -2111 variant, but it looks pretty broken.

We refuse to decode the -2112 variant. This is #21259.

Manual tests for now, but having these in tree will make it easier
to write unit tests later, once things work better.

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

You can watch videos of the system being developed on YouTube:

Features

  • Modern x86 64-bit kernel with pre-emptive multi-threading
  • Browser with JavaScript, WebAssembly, and more (check the spec compliance for JS, CSS, and Wasm)
  • Security features (hardware protections, limited userland capabilities, W^X memory, pledge & unveil, (K)ASLR, OOM-resistance, web-content isolation, state-of-the-art TLS algorithms, ...)
  • System services (WindowServer, LoginServer, AudioServer, WebServer, RequestServer, CrashServer, ...) and modern IPC
  • Good POSIX compatibility (LibC, Shell, syscalls, signals, pseudoterminals, filesystem notifications, standard Unix utilities, ...)
  • POSIX-like virtual file systems (/proc, /dev, /sys, /tmp, ...) and ext2 file system
  • Network stack and applications with support for IPv4, TCP, UDP; DNS, HTTP, Gemini, IMAP, NTP
  • Profiling, debugging and other development tools (Kernel-supported profiling, detailed program analysis with software emulation in UserspaceEmulator, CrashReporter, interactive GUI playground, HexEditor, HackStudio IDE for C++ and more)
  • Libraries for everything from cryptography to OpenGL, audio, JavaScript, GUI, playing chess, ...
  • Support for many common and uncommon file formats (PNG, JPEG, GIF, MP3, WAV, FLAC, ZIP, TAR, PDF, QOI, Gemini, ...)
  • Unified style and design philosophy, flexible theming system, custom (bitmap and vector) fonts
  • Games (Solitaire, Minesweeper, 2048, chess, Conway's Game of Life, ...) and demos (CatDog, Starfield, Eyes, mandelbrot set, WidgetGallery, ...)
  • Every-day GUI programs and utilities (Spreadsheet with JavaScript, TextEditor, Terminal, PixelPaint, various multimedia viewers and players, Mail, Assistant, Calculator, ...)

... and all of the above are right in this repository, no extra dependencies, built from-scratch by us :^)

Additionally, there are over three hundred ports of popular open-source software, including games, compilers, Unix tools, multimedia apps and more.

How do I read the documentation?

Man pages are available online at man.serenityos.org. These pages are generated from the Markdown source files in Base/usr/share/man and updated automatically.

When running SerenityOS you can use man for the terminal interface, or help for the GUI.

Code-related documentation can be found in the documentation folder.

How do I build and run this?

See the SerenityOS build instructions. Serenity runs on Linux, macOS (aarch64 might be a challenge), Windows (with WSL2) and many other *Nixes with hardware or software virtualization.
