Create COMPLIANCE document describing metacity specification compliance. 2003-11-16 Rob Adams <readams@readams.net> Create COMPLIANCE document describing metacity specification compliance. Right now gives detailed EWMH compliance; still need to add ICCCM compliance information. Also some minor fixes to bring metacity into compliance on some points. * COMPLIANCE: new file * src/display.h, src/display.c (meta_display_open), src/screen.c (set_supported_hint): add atom_net_wm_action_fullscreen and atom_net_wm_action_minimize * src/window.c (set_allowed_actions_hint): some fixes to which hints to set and add fullscreen and minimize.

The title indicates a feature or a hint in the specification, and the
version number indicates the minimum version of the specification
supported by metacity. Later versions may be supported if no
incompatible changes have been made in the specification.

maximization states. Currently metacity will do a two-dimensional
maximization if either property is set.
