Start of integration of Erwann Chenede's multihead work
from the gtk-multihead branch.
* gdk/gdkdisplay.[ch] gdk/gdkscreen.[ch]
gdk/x11/gdkdisplay-x11.[ch] gdk/x11/gdkscreen-x11.[ch]
New classes representing a set of screens with attached
input devices and a single contiguous area, respectively.
* gdk/gdk.[ch] gdk/gdkinternals.h gdk/x11/gdkmain-x11.c:
gdk/x11/gdkprivate-x11.h: Make the initialization interface
simple _gdk_windowing_init() and do the rest in
gdk_open_display() calls.
* gdk/gdk.[ch]: Add gdk_parse_args() which can be used
to do the display-independent part of initialization
instead of gdk_init_[check].
* gdk/gdkcursor.h gdk/gdkfont.h gdk/gdkkeys.h gdk/gdkpixmap.h
gdk/gdkproperty.h gdk/gdkselection.h gdk/gdkwindow.h:
Add multihead variants (_for_display(), for_screen()) of functions
getting information specific to a particular screen screen or
display.
* gdk/gdkscreen.[ch]: Add gdk_screen__* variants of functions
like gdk_rgb_get_colormap() that used to get/list global
objects.
* gdk/x11/gdkx.h: Add functions for converting GdkScreen
and GdkDisplay into the X equivalents.
* gdk/x11/gdkwindow-x11.c: Removed gdk_window_xid_at_coords()
not in the headers and unused.
* configure.in gdk/x11/{gxid.c,gxid_lib.[ch],gdkinput-gxi.c}:
Remove gxid support ... has not been tested for a long time...
"xfree" support is more portable to non XFree86.
* gdk/**.h: Add a GDK_MULTIHEAD_SAFE define that can be
used to turn off functions that are inherently non-multihead
safe.
* gdk/**.c: add GDK_NOTE(multihead, ...) calls when functions
are used in non-multihead-safe ways.
* gdk/*.c gdk/x11/*.c: Changes to make the internals of GDK
multihead safe.
