New release function _gdk_quartz_drag_source_context_destroy_gtk_only
gets called when drag fails to start or is cancelled as well as
when it successfully completes.
Some applications need to access gdk_quartz_window_get_nsview,
gdk_quartz_window_get_nswindow, and gdk_quartz_event_get_nsevent
so move these from the private gdkquartz-gtk-only.h to a new
header gdkquartz-cocoa-access.h. Don't include this header in
gdkquartz.h so that user code that doesn't need to access these
functins isn't required to compile with Objective C/C++.

Don't export any functions taking or returning MacOS types in
gdkquartz.h, gdkprivate-quartz.h, or any header that either includes.
The GdkQuartz internal functions are moved to a new header
gdkinternal-quartz.h, the functions used by quartz-specific
Gtk files are moved to another new header gdkquartz-gtk-only.h, and
the key and event enums to a new header gdkkeys-quartz.h.
Instead of storing the dnd icon as a pixbuf store it
as a cairo surface and transfer the device scale
when converting it to a NSImage. In the pixbuf/stock/named
setters convert to a surface instead (no hidpi support yet)
We've recently a number of classes wholly. For these cases,
move the headers and sources to gtk/deprecated/ and adjust
Makefiles and includes accordingly.
Affected classes:
GtkAction
GtkActionGroup
GtkActivatable
GtkIconFactory
GtkImageMenuItem
GtkRadioAction
GtkRecentAction
GtkStock
GtkToggleAction
GtkUIManager
Of course, we must pass coordinates in the NSWindow coordinate system
when creating an NSEvent. This fixes drag icon positioning and makes
the icon slide back to the correct position when the drag is
canceled.
If a zero-sized NSImage calls lockfocus it throws an exception. Make sure that the image isn't zero-sized before calling lockfocus, and log a warning and return NULL if it is zero-sized.
Have the quartz version of gtk_drag_begin_idle return FALSE if the returned image is NULL.
If _gtk_quartz_create_image_from_pixbuf is given a pixbuf with size 0, 0
or which produces an NSImage with size 0.0, 0.0, it throws an exception
which Gtk doesn't handle.
your changes. Lines starting
Create a synthetic NSMouseLeftDown to store in the GtkQuartzDragSourceInfo
rather than relying on the NSWindow's latest event being the right one (or the
right kind).
Clear the Drag paste board just before the info->context is released.
This way the GtkDragSourceOwner is released just before the drag context
is and thus can pasteboard:provideDataForType: not accidentally access
an already released drag context
