The rfb standard keeps envolving.  While the official spec is kind of
frozen since a decade or so the community maintains an updated version
of the spec at:

This series adds support for two new extensions from that spec: alpha
cursor and extended desktop resize.

alpha cursor allows a full alpha channel for the cursor image (unlike
the rich cursor extension which has only a bitmask for transparency).

extended desktop resize makes the desktop-resize work both ways, i.e. we
can not only signal guest display resolution changes to the vnc client
but also vnc client window size changes to the guest.

Tested with tigervnc.

Support for gtk-vnc is in progress.

 - dropped cursor patches (already merged).
 - fix client initialization (reply to update request not set encoding).

 - dropped qxl bits (will be a separate patch series).
 - use error codes for desktop resize responses.
 - little tweaks here and there.
 - pick up some review tags.

Gerd Hoffmann (3):
  vnc: move check into vnc_cursor_define
  vnc: move initialization to framebuffer_update_request
  vnc: add support for extended desktop resize
