 /* NOTES
    - The encoder dumps uint16_t numbers as is into GIF files, which means it
      only works on little-endian machines, since this is what GIF requires.
-   - The encoder is very limited:
-     * the global palette size is fixed in 16 colors;
-     * there's no way to add local palettes;
-     * the only GIF89a extension implemented is GCE (to set delay times).
-   - The compressor only sends the clear code once per image, as the first
-     code (no adaptive compression technique is employed). This is suboptimal
-     for large and complex images.
