Merge branch 'master' into 'master'
Use open-default-display instead of open-display. See merge request !6
This commit breaks clim-tos on Windows and SBCL, because the definition of
xlib::get-default-displaythat gets called from
xlib:open-default-displayis wrapped in
:unixis not present in
*features*on Windows, so
xlib::get-default-displayends up undefined. Oddly, this doesn't stop McCLIM from working on the same configuration.
