per-screen. Duh. * xterm.c (x_wm_set_window_state, x_wm_set_icon_pixmap, x_wm_set_icon_position): Use F->display.x->wm_hints, rather than x_wm_hints. (x_term_init): Don't initialize x_wm_hints here. * xterm.c (x_set_text_property): Properly balance the BLOCK_INPUTs and UNBLOCK_INPUTs. And remember that VALUE is the strin we want to set the name to, not PROPERTY. * xterm.c (x_set_text_property): Define this appropriately for X11R3 and X11R4. * xterm.c (x_set_text_property): Make this take a Lisp_Object string as an argument, rather than a pointer and a length. * xterm.c: Doc fixes. * xterm.c [USG5]: Don't include <sys/types.h>. * xterm.c (x_make_frame_invisible): Instead of calling XWithdraw window, which isn't widely available, write out what it does, since that's not much. (x_iconify_frame): Explicitly perform both the X11R3 and X11R4 methods for iconification; don't use XIconifyWindow, since that's not present in R3. * xterm.c (x_wm_set_size_hint): Don't bother setting the base_width and base_height members; their function is performed just as well by the min_width and min_height members, and if we use XSetNormalHints instead of XSetWMNormalHints, we can be compatible with R3. * xterm.c (x_error_handler): There is no way to invoke the default error handler which works on all versions of X11, so don't bother; call XGetErrorText and print the message ourselves. * xterm.c (x_term_init): Don't use MAXHOSTNAMELEN; this isn't defined on all systems. Since we only use that as an initial guess anyway, it's not very important. * xterm.c (x_set_text_property): New function.
