[Qemu-devel] [PATCH 16/16] vnc: tight: don't limit png rect size

[Corentin Chary <corentincj@iksaif.net>]

PNG was introduced because some vnc HTML5 clients like noVNC
have slow zlib decoding, but really fast PNG rendering. This
means that if PNG is enabled we should send only PNG (and JPEG, fill),
and never something compressed directly with zlib.
