[cl-cairo2-announce] new cl-cairo2 version -- now reworked x11 support

[Tamas K Papp]

Hi,

I have just uploaded the latest version of cl-cairo2.  I have
completely rewritten the X11 support, with the following changes:

- everything is done via CFFI, no C code or shared library to install,
  this is much easier to debug
- multiple displays are supported
- there is one event loop per display, this is much easier to manage
