997e8c1ae1 GDK W32: Adapt to dest_surface removal, misc changes 
* There's no GdkDragContext->dest_surface anymore.
  Add dest_window field to GdkWin32DragContext,
  and use that instead.
* Remove unused function prototypes
* Add more comments
* Rename variables and fields from 'window' to 'surface'
  where appropriate
* Fix header indentation a bit
* Try to ensure that uninitialized/unknown handle variables
  and fields are set to INVALID_HANDLE_VALUE instead of NULL,
  as there may be cases where NULL is a valid handle value.

8ee4de804c GDK W32: Adapt to GdkDrop and GdkDragContext changes 
* Remove clipdrop->dnd_target_state, it's not used anymore
* Remove non-functioning _gdk_dropfiles_store(), store dropfiles
  list in GdkWin32Drop instead
* Fix multiple comment typos
* Fix _gdk_win32_get_clipboard_format_name_as_interned_mimetype() to
  leave names that look like mime/types alone
* Refactor _gdk_win32_add_w32format_to_pairs() to populate
  GdkContentFormatsBuilder directly, instead of making a GList
* Rename context -> drag (still using GdkDragContext type,
  but [almost?] all variables and comments say "drag" now)
* Rename GdkDropContext -> GdkDrop
* Rename some parameter names for clarity
* Rewrite local protocol to look more like OLE2 protocol
  instead of mirroring the structure of the X11 API.
* Add handle_events field to GdkWin32DragContext,
  to shut off event handling (temporary fix until GTK is patched up)
* Remove _gdk_win32_drag_context_find() - the drag object is stored
  in GdkDrop instead. Use _gdk_win32_find_drag_for_dest_surface()
  to get it initially.
* Remove target_ctx_for_window, droptarget context is stored
  in the surface instead.
* Call gdk_drag_context_set_cursor() just like wayland backend does
  (slightly broken for now)
* Clean up the action choosing code (filter source actions by using
  keyboard state, pass that to GTK, get all actions supported by GTK in
  response, match them up with filtered source actions, return the
  result, falling back to COPY in case of multiple actions)
* Check drag_win32->protocol instead of the use_ole2_dnd variable where
  possible
* Remove protocol checks from functions that are only used by the local
  protocol
* Use event state to manufacture the keyboard state for WM_MOUSEMOVE
* Change function names printed by GDK_NOTE to name the actual
  functions, not their theoretical generic GDK stack ancestors
* Consistently use drag_win32 and drop_win32 variables instead of a mix
  of that and win32_drag/win32_drop
* Return FALSE from button handler to ensure that GTK gets the button
  event to break implicit grab
* Emit leave event on failed idroptarget_drop() calls

54a4307128 GDK W32: Another massive clipboard and DnD update 
Rename GdkWin32Selection to GdkWin32Clipdrop, since GdkSelection
is mostly gone, and the word "selection" does not reflect the
functionality of this object too well.

Clipboard is now handled by a separate thread, most of the code for
it now lives in gdkclipdrop-win32.c, gdkclipboard-win32.c just uses
clipdrop as a backend.

The DnD source part is also put into a thread.
The DnD target part does not spin the main loop, it just
emits a GDK event and returns a default value if it doesn't get a reply
by the time the event is processed.

Both clipboard and DnD use a new GOutputStream subclass to get data
from GTK and put it into a HGLOBAL.

GdkWin32DragContext is split into GdkWin32DragContext and GdkWin32DropContext,
anticipating a similar change that slated to happen to GdkDragContext.

OLE2 DnD protocol is now used by default, set GDK_WIN32_OLE2_DND envvar to 0
to make GDK use the old LOCAL and DROPFILES protocols.

6c29e81051 W32: Massive W32 DnD fix 
Massive changes to OLE2 DnD protocol, which was completely broken before:
* Keep GdkDragContext and OLE2 objects separate (don't ref/unref them
  together, don't necessarily create them together).
* Keep IDataObject formats in the object itself, not in a global variable.
* Fix getdata() to look up the request target in its format list, not in the
  global hash table
* Create target GdkDragContext on each drag_enter, destroy it on drag_leave,
  whereas IDropTarget is created when a window becomes a drag destination
  and is re-used indefinitely.
* Query the source IDataObject for its supported types, cache them in the
  target (!) context. This is how GTK+ works, honestly.
* Remember current_src_object when we initiate a drag, to be able
  to detect later on that the data object is ours and use a
  shortcut when querying targets
* Make sure GDK_DRAG_MOTION is only sent when something changes
* Support GTK drag cursors
* Ensure that exotic GTK clipboard formats are registered
  (but try to avoid registering formats that can't be used between applications).
* Don't enumerate internal formats
* Ensure that DnD indicator window can't accept drags or receive any kind of input
  (use WS_EX_TRANSPARENT).
* Remove unneeded indentation in _gdk_win32_dnd_do_dragdrop()
* Fix indentation in gdk_win32_drag_context_drop_finish()
* Remove obsolete comments in _gdk_win32_window_register_dnd()
* Check for DnD in progress when processing WM_KILLFOCUS, don't emit a grab
  break event in such cases (this allows alt-tabbing while DnD is in progress,
  though there may be lingering issues with focus after dropping...)
* Support Shell ID List -> text/uri-list conversion, now it's possible
  to drop files (dragged from Explorer) on GTK+ applications
* Explicitly use RegisterClipboardFormatA() when we know that the string
  is not in unicode. Otherwise explicitly use RegisterClipboardFormatW()
  with a UTF8->UTF16 converted string
* Fix _gdk_win32_display_get_selection_owner() to correctly bail
  when selection owner HWND is NULL (looking up GdkWindow for NULL
  HWND always succeeds and returns the root window - not the intended
  effect)
* More logging
* Send DROP_FINISHED event after DnD loop ends
* Send STATUS event on feedback
* Move GetKeyboardState() and related code into _gdk_win32_window_drag_begin(),
  so that it's closer to the point where last_pt and start_pt are set
* Use & 0x80 to check for the key being pressed. Windows will set low-order bit
  to 1 for all mouse buttons to indicate that they are toggled, so simply
  checking for the value not being 0 is not enough anymore.
  This is probably a new thing in modern W32 that didn't exist before
  (OLE2 DnD code is old).
* Fixed (hopefully) and simplified HiDPI parts of the code.

Also adds managed DnD implementation for W32 GDK backend (for both
OLE2 and LOCAL protocols). Mostly a copy of the X11 backend code, but
there are some minor differences:
* doesn't use drag_window field in GdkDragContext,
  uses the one in GdkWin32DragContext exclusively
* subtracts hotspot offset from the window coordinates when showing
  the dragback animation
* tries to consistently support scaling and caches the scale
  in the context
* Some keynav code is removed (places where grabbing/ungrabbing should
  happen is marked with TODOs), and the rest is probably inert.

Also significantly changes the way selection (and clipboard) is handled
(as MSDN rightly notes, the handling for DnD and Clipboard
 formats is virtually the same, so it makes sense to handle
 both with the same code):
* Don't spam GDK_OWNER_CHANGE, send them only when owner
  actually changes
* Open clipboard when our process becomes the clipboard owner
  (we are doing it anyway, to empty the clipboard and *become* the owner),
  and then don't close it until a scheduled selection request event
  (with TARGETS target) is received. Process that event by announcing
  all of our supported formats (by that time add_targets() should have
  been called up the stack, thus the formats are known; just in case,
  add_targets() will also schedule a selection request, if one isn't
  scheduled already, so that late-coming formats can still be announced).
* Allow clipboard opening for selection_convert() to be delayed if it
  fails initially.
* The last two points above should fix all the bugs about GTK+ rising
  too much ruckus over OpenClipboard() failures, as owner change
  *is allowed* to fail (though not all callers currently handle
  that case), and selection_convert() is asynchronous to begin with.
  Still, this is somewhat risky, as there's a possibility that the
  code will work in unexpected ways and the clipboard will remain open.
  There's now logging to track the clipboard being opened and closed,
  and a number of failsafes that try to ensure that it isn't kept open
  for no reason.
* Added copious notes on the way clipboard works on X11, Windows and GDK-W32,
  also removed old comments in DnD implementation, replaced some of them
  with the new ones
* A lot of crufty module-global variables are stuffed into a singleton
  object, GdkWin32Selection. It's technically possible to make it a
  sub-object of the Display object (the way Wayland backend does),
  but since Display object on W32 is a singleton anyway... why bother?
* Fixed the send_change_events() a bit (was slightly broken in one of the
  previous iterations)
* Ensure that there's no confusion between selection conversion (an artifact
  term from X11) and selection transmutation (changing the data to be W32-compatible)
* Put all the transmutation code and format-target-matching code into gdkselection-win32.c,
  now this code isn't spread across multiple files.
* Consequently, moved some code away from gdkproperty-win32.c and gdkdnd-win32.c
* Extensive format transmutation checks for OLE2 DnD and clipboard.
  We now keep track of which format mappings are for transmutations,
  and which aren't (for example, when formats are passed as-is, or when
  a registered name is just an alias)
* Put transmutation code into separate functions

* Ensure that drop target keeps a format->target map for supported formats,
  this is useful when selection_convert() is called, as it only receives a
  single target and no hints on the format from which the data should
  be transmuted into this target.
* Add clear_targets() on W32, to de called by GTK
* Use g_set_object() instead of g_ref_object() where it is allowed.
* Fix indentation (and convert tabs to spaces), remove unused variables
