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.
