  1. Building with AVIF support requires the C library dav1d and is therefore not enabled by default.
  2. SVGs are rastarized because Simp is primarily a bitmap image editor.
  3. Most common cameras are supported but the colors may look weird because the standard curve may not fit all images.
  4. HEIF/HEIC is only enabled on linux by default.
  5. JPEG XL is only works well on linux currently.
