[PATCH 0/9] vnc: support some new extensions.

[Gerd Hoffmann <kraxel@redhat.com>]

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:
	https://github.com/rfbproto/rfbproto/

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.

gtk-vnc (and anything building on top of it like virt-viewer and
virt-manager) has no support for these extensions.

Gerd Hoffmann (9):
  console: allow con==NULL in dpy_set_ui_info
  console: add check for ui_info pointer
  vnc: use enum for features
  vnc: drop unused copyrect feature
  vnc: add pseudo encodings
  vnc: add alpha cursor support
  vnc: force initial resize message
  vnc: add support for extended desktop resize
  qxl: add ui_info callback
