c89c19d2f9 GDK W32: Make sure drag source window is not NULL
This prevents GTK from throwing a bunch of warnings when it tries
to get drag source window -> screen of that window -> ipc widget for that screen,
and then tries to attach a signal handler to that widget.

Specifically, this happens when we get a DnD move from another
application.

f0d04f82f8 GDK W32: Special handling for DELETE requests
1) Ensure that any DELETE requests from the target are sent to GDK, even if
   both the source and the target are in the same process and it
   is therefore possible to use a shortcut and call the handler directly
   in GTK layer
2) Ensure that target GDK doesn't do anything when GTK asks it to send
   a DELETE request, just report back immediately (the code up the stack
   does not check for successfullness when request is DELETE, so not giving
   it any data is OK).

The source code already synthesizes a DELETE request, so that side is
also taken care of.

5e2e0af8b4 GDK W32: Preserve the target value for change_property()
We need to know the target atom value to know when we need to
do something with side-effects (since side-effects are expressed via
special target values). Previously, the code side-stepped that by looking
at the data type (which was rather unique for the one side-effect
target that we supported, signalled by the TARGETS target),
but for the DELETE target that seems to be no longer an option, hence the new
field to carry this information past the convert_selection() routine.

This prevents GDK from throwing a warning when trying to convert
a DELETE target, which has no format or data objects set.

The side-effects for the DELETE target happen earlier, in GTK layer.
By the point it gets to change_property(), it's a no-op.

5d0bfdd840 GDK W32: Ensure that selection request is processed
To do that, run the message loop for one second or until the side-effect
of running the selection request handler is achieved (as opposed to
running it until the event is no longer queued).

The disavantage of this method is that if the event handling is
somehow missed (due to a variety of reasons - after all, it's not
a straight path from an event being queued to property_change()
being called), this will loop for one second. Since we do process
events during that time, this will not hang the application, but
might still restrict some of the functionality.

a66017a6a0 GDK W32: Refuse to release mouse grab while in DnD mode
Handle WM_CANCELMODE and do nothing in response to it when DnD is
active. Otherwise pass it to DefWindowProc, which will call ReleaseCapture()
on our behalf.
This prevents us from losing mouse capture when alt-tabbing during DnD
(this includes the feature of Windows Explorer where dragging stuff over
a window button in the taskbar causes that window to receive focus, i.e.
keyboardless alt-tabbing).

6d37ed6256 GDK W32: Update layered windows on opacity changes
Without this patch layered windows are only updated when they are moved
by the user or then their contents changes. This patch adds opacity
changes to the list of things that make GDK update a window. Without this
windows that don't redraw and are not moved by the used (DnD drag indicator
windows, for example) don't change their opacity.

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

33de691d9f GDK W32: More flexible modal operation mode
Instead of using a boolean to indicate a modal operation being in progress,
use a set of flags, and allow these to be set and unset independently.

Specifically, this allows WM_CAPTURECHANGED handler to only act when a drag-move or
drag-resize modal operation is in progress, and ignore DND (which can also cause
WM_CAPTURECHANGED to be posted). This avoids a crash due to assertion failure when
OLE2 DND code tries to end a modal operation that was already ended by the WM_CAPTURECHANGED
handler.

eb6d5b6b27 GDK-Win32: Fix AeroSnap on HiDPI
Commit 1d0fad3 revealed that there were some assumptions made that were
actually to compensate for the bug fixed by that commit, so we need to
remove those assumptions as they would result in AerSnap to not work
properly on HiDPI screens.

Also re-do how we set the x and y positions of our GdkWindow, so that we
are more consistent across the board when we go between a GDK window
coordinate and a Windows API window cooredinate.

This would also simplify the code a bit.

d7e2017c28 GDK W32: Handle drivers that do not send WT_CSRCHANGE after WT_PROXIMITY
Some drivers don't do that (not sure whether that is the correct behaviour
or not). Remember each WT_PROXIMITY with LOWORD(lParam) != 0 that we get,
then look for a WT_CSRCHANGE. If WT_CSRCHANGE doesn't come, but a WT_PACKET
does, assume that this device is the one that sent WT_PROXIMITY.

Also include fallback code to ensure that WT_PACKETs for an enabled device
disable the system pointer, because WT_PROXIMITY handler might have
enabled it by mistake, since it's not possible to know which device left
the proximity (it might have been a disabled device).

3c9b667d3e GDK W32: Apply HiDPI scale properly to monitors
Previously HiDPI scale was retrieved and applied too late in the initialization
process to affect monitor size and monitor workarea size, but the code that
initializes these sizes *did* try to use the scale, even though it was always
getting scale=1.

To fix this, move the too-late code into monitor enumeration routine.
This also fixes a probable semantic bug where width and height were divided
by scale, again.

Now monitor and workarea should be in application pixels (i.e. divided by scale),
as intended.

58ba4d6a3e GDK W32: Ensure that we use made-up monitors when there are none
Previously GDK only made up monitors when it initially found none. Now it
also makes up monitors when it initially finds some, but later fails to get
their informatin in a normal way and finally prunes them out, being left with
zero monitors.

Having zero-length monitor array is unexpected and causes a number
of critical warnings and some critical functionality (such as displaying
drop-down menus) fails in such cases.

Ideally, there might be such a way to interrogate W32 API that produces the
information about non-real (but active) monitors out of it so that it isn't
necessary for us to make stuff up. However, this code is already complicated,
and i am not prepared to dig W32 API to find a way to do this.

This fixes the issues people had when they accessed a Windows desktop via RDP.

c36d66bdb6 GDK W32: Use keyboard hook to detect AeroSnap combinations better
Windows WM handles AeroSnap for normal windows on keydown. We did this
on keyup only because we do not get a keydown message, even if Windows WM
does nothing with a combination. However, in some specific cases it DOES
do something - and we have no way to detect that. Specifically, winkey+downarrow
causes maximized window to be restored by WM, and GDK fails to detect that. Then
GDK gets a keyup message, figures that winkey+downarrow was pressed and released,
and handles the combination - by minimizing the window.

To overcome this, install a low-level keyboard hook (high-level ones have
the same problem as normal message loop - they don't get messages when
Windows WM handles combinations) and use it to detect interesting key combinations
before Windows WM has a chance to block them from being processed.

Once an interesting combination is detected, post a message to the window, which
will be handled in due order.

It should be noted that this code handles key repetitions in a very crude manner.

The downside is that AeroSnap will not work if hook installation function call fails.
Also, this is a global hook, and if the hook procedure does something wrong, bad things
can happen.

cba75d8239 GDK W32: Handle CapsLock as part of the key shift level
Instead of using some kind of flawed logic about modifying a keypress result
when CapsLock is toggled, just add a CapsLock shift level (and all derived
shift levels, i.e. Shift+CapsLock and CapsLock+AltGr and Shift+CapsLock+AltGr)
and query Windows keyboard layout API about the result of keypresses involving
CapsLock.

Keysym table is going to be (roughly) twice as large now, but CapsLock'ed
keypresses will give correct results for some keyboard layouts (such as
Czech keyboard layout, which without this change produces lowercase letters
for CapsLock->[0,2,3,4...] instead of uppercase ones).

Keymap update time also increases accordingly.

e076cc7b1f GDK/Win32: Fix build after GDK Root Window and DND changes
Ensure that things build again, and instead use the Windows API to
acquire the screen dimensions (note: this may need to be scaled for
HiDPI, but since I do not own a WinTab-based device, I will need to
keep the dimensions as-is for now).

Also update the gdkdnd-win32.c code to use formats rather than targets.
