... rather than whether it currently has one.
This is for OpenGLSurfaceMode=behind. In that mode, we need to make the window
transparent wherever a GL-rendered view should not be clipped by GDI-rendered
children or sibling views.
Some apps attach a GL context to the view only temporarily, do some rendering,
and then detach it. But the GL surface remains, with the rendered graphics.
In order for those to show, the window needs to remain transparent even though
none of its views has a GL context currently attached.

The code had been handling ordering sibling windows relative to each other,
including windows neither of which were child windows. However, it wasn't
properly handling other relationships (e.g. cousins, nieces, uncles, etc.).
The reason this is complicated is that Cocoa keeps child windows in a fixed
relative order to their parent and siblings. The normal -orderWindow:relativeTo:
method doesn't work. One has to remove the children from the parent and re-add
them in the desired order.

Cocoa does this automatically for non-owned windows and informs the back end
via a different mechanism (WINDOW_BROUGHT_FORWARD). However, for owned windows
(child windows in Cocoa parlance), Cocoa does not change their z-order relative
to the owner (parent) or sibling owned windows when clicked. So, we have to
move the window in user32's z-order so that it gets moved appropriately on
screen in response.

We had been posting it when exiting fullscreen mode ended. However, certain
events during exiting could provoke the back-end to assert the window frame as
it knows it, which would be the one from full-screen mode. This would be
handled by the Cocoa thread after exiting full-screen mode. So, the window
would animate to its pre-fullscreen frame and then spontaneously go back to
covering the screen. This would be Windows-style fullscreen rather than
Cocoa-style and there'd be no obvious way to get out.
The problem occurs on macOS 10.12 (Sierra) due to a change in what methods it
calls on the window while exiting fullscreen.

When a window is shown, it may not have drawn its content into the backing
surface, yet. Cocoa will draw the window, starting with its standard light
gray background and then the content view. However, the content view won't
have anything to draw, yet, though, so the window background is not drawn over.
A short while later, usually, the app will paint its content into the window
backing surface and Cocoa will be told to redraw the window. This works, but
the user can often see the flash of the window background color first. This
is especially visible for windows with dark content.
Part of the fix is to set the window background to transparent until the
content view has actually drawn once since the window was shown.
That's not sufficient on its own, though. We had disabled Cocoa's automatic
display mechanism for windows and put display on a display-link timer. This
meant that the window was not actually cleared to its transparent color. When
the window was shown, the Window Server displayed a white backing buffer. It
is the app process which should fill that backing buffer with clear color but,
because we had disabled auto-display, that wasn't getting done at the same
time the window was displayed. It was happening some time after. Again, the
result was a visible flicker of white.
So, we now temporarily re-enable auto-display just before showing a window.

When this Retina mode is enabled and the primary display is in the user's
default configuration, Wine gets told that screen and window sizes and mouse
coordinates are twice what Cocoa reports them as in its virtual coordinate
system ("points"). The Windows apps then renders at that high resolution and
the Mac driver blits it to screen. If the screen is actually a Retina display
in a high-DPI mode, then this extra detail will be preserved. Otherwise, the
rendering will be downsampled and blurry.
This is intended to be combined with increasing the Windows DPI, as via winecfg.
If that is doubled to 192, then, in theory, graphical elements will remain the
same visual size on screen but be rendered with finer detail. Unfortunately,
many Windows programs don't correctly handle non-standard DPI so the results
are not always perfect.
The registry setting to enable Retina mode is:
[HKEY_CURRENT_USER\Software\Wine\Mac Driver]
"RetinaMode"="y"
Note that this setting is not looked for in the AppDefaults\<exe name> key
because it doesn't make sense for only some processes in a Wine session to see
the high-resolution sizes and coordinates.

The change to a CVDisplayLink-driven display mechanism introduced a problem: a
Wine process never went completely idle for long periods. The display link
would fire for every refresh cycle of the display, waking a CPU from idle and
wasting energy.
To fix that, I have the display link stop itself when it determines that none
of its windows need to be displayed. When a window is subsequently marked as
needing display, it either temporarily re-enables Cocoa's normal autodisplay
mechanism so that it displays at the end of the current turn of the run loop,
or it restarts the display link. It chooses the former if it's been a long
time since the window was last displayed so that the display is done more
immediately.

Some Windows apps cause user32 to flush the window surface much faster than the
display refresh rate. The Mac driver only marks its window as needing to be
redrawn and lets Cocoa decide how often to actually redraw. Unfortunately,
Cocoa redraws each time through the run loop and, since the Mac driver uses a
run loop source to convey messages from background threads to the main thread,
it redraws after every batch of messages.
On some versions of OS X, this excessive drawing provokes synchronization with
the window server's buffer swaps, preventing the main thread from being
responsive. Even when that doesn't happen, it's wasteful.
So, we set our windows' autodisplay property to false so that Cocoa never
displays windows itself. Then, we arrange to call -displayIfNeeded once per
display refresh cycle using a CVDisplayLink. We maintain one CVDisplayLink per
display (on demand), move windows among them as the windows change screens,
start them when they acquire their first window, and stop them when they have
none left.

Some apps create a zero-sized window as their "main" window and then create
all of the other top-level windows as owned windows with that main window as
the owner. The user interacts with these owned windows. When the user
attempts to minimize one of these owned windows, the app instead minimizes the
zero-sized owner window. When an owner window is minimized, all of its owned
windows are hidden.
The Mac driver faithfully carries out these window operations. The only
visible windows are hidden and the zero-sized window is minimized. This
results in an invisible animation of the window down to a slot in the Dock -
a slot which appears mostly empty. The invisible window thumbnail is badged
with the app icon, but it still looks strange.
On Windows, the Alt-Tab switcher uses the image of the owned window to
represent the zero-sized owner.
This commit attempts to do something similar. It takes over drawing of the
Dock icon for minimized, zero-sized window. It grabs a snapshot of one of the
owned windows and draws the app badge onto it. Since the owned windows are
hidden before the zero-sized owner is minimized and we can't take snapshots of
hidden windows, we use heuristics to guess when it may be useful to grab the
snapshot. If the user minimizes an owned window from the Cocoa side, we grab
that window's snapshot. If an owned window is being hidden and no snapshot has
been taken recently, we grab its snapshot on the theory that this may be the
beginning of hiding all of the owned windows before minimizing the owner.
Unfortunately, this doesn't address the invisible animations when minimizing
and unminimizing the zero-sized owner window.

When the display mode changes such that the screen height changes, we'd like
our windows to keep their position relative to the top-left of the primary
screen. That's how WinAPI's coordinate system works and we want the WinAPI
position of the window to not change just because the display mode changed.
Unfortunately that's not achievable in Cocoa. Cocoa keeps the window
stationary relative to the screen it's on, not necessarily the primary screen,
and it's sometimes relative to the bottom-left and sometimes the top-left of
that screen.
So, what we do instead is queue an event to get the back end to reassert the
WinAPI position of the window. This is queued before Cocoa can adjust the
Cocoa position of the window which would queue a WINDOW_FRAME_CHANGED to the
back end and mess up the WinAPI position. The back end's reassertion of the
WinAPI position won't be processed by the Cocoa thread until after Cocoa has
adjusted the position and will thus override it. It will also discard any
wrong WINDOW_FRAME_CHANGED that may have been queued.

The default behavior is that GL surfaces are on top of all non-GL content in
the window. This maximizes the performance for the common case of games, but
clipping by parents, siblings, and child windows isn't respected.
Setting OpenGLSurfaceMode to "behind" pushes the GL surface to be behind the
Mac window. The window has transparent holes punched through it so that the GL
surface shows through. USER32 and the wineserver take care of making sure the
holes are only where the GL windows would be unclipped and unoccluded. Because
the OS X window server has to composite the GL surface with the window, this
limits the framerate.
Since the Mac driver has no server-side rendering path, GDI rendering to a
window which has a GL surface doesn't work. As a partial workaround, mostly
for cases where a GL surface is created but never used, setting
OpenGLSurfaceMode to "transparent" allows the GDI rendering to show through the
transparent parts of the GL surface. The GDI rendering is drawn to the
top-level window's surface as normal. (The behavior of user32 to exclude the
portion covered by a GL window from GDI rendering is disabled.) The GL surface
is in front of the window but potentially wholly or partially transparent. It
is composited with the window behind it.
The GL surface is initially cleared to be completely transparent. So, if
no GL rendering is done, the window will appear as though the GL surface didn't
exist.
OS X doesn't have the same concept of maximized windows as Windows does.
There's no mode that prevents a normally-movable window from being moved. If
a window is "zoomed", it mostly fills the screen but the user can still move
or resize it, at which point it ceases to be in the zoomed state. So, users
are confused and frustrated when they can't move a window that's maximized.
To get similar behavior while still respecting Win32 semantics, we detect when
the user tries to move a maximized window. When they start, a request is
submitted to the app to restore the window. Unless and until the window is
restored, we don't actually allow the window to move.
The user expects to move the window from its current (maximized) position. It
should not jump to its normal position upon being restored. So, we set the
window's normal position to its current position before restoring it.

If a window is "zoomed", it mostly fills the screen but the user can still

To get similar behavior while still respecting Win32 semantics, we now let the
user try to resize maximized windows. (The resize cursors are shown at the
edges of the window frame.) When they start, a request is submitted to the app

actually allow the window to change its size.
The user expects to resize the window from its current (maximized) position.
It should not jump to its normal position upon being restored. So, we set the

OS X doesn't really have the concept of windows being maximized; that is, being
in a mode where they can't be moved or resized. As a consequence, it doesn't
have a button in the window title bar to restore a maximized window to normal.
So, when a Wine window is maximized, the Mac driver hijacks the green zoom
button to act as a restore button. (When a window is zoomed, the green button
"unzooms" back to its last user size and position, so it's analogous.)
However, with OS X 10.10 (Yosemite), the green button prefers to act as a
toggle for the Cocoa full-screen mode rather than zooming and unzooming. This
made it difficult for users to restore a maximized window. They would have to
Option-click the green button, double-click the title bar, or choose Zoom
from the Window menu, none of which is obvious.
The fix is to disable Cocoa full-screen mode for maximized windows. Then, the
green button reverts to unzoom and restoring the window.
Status items are the things on the right end of the Mac menu bar, like the
clock and volume widget. It turns out that they are displayed at a higher
window level than everything else in the menu bar. For the case where the
displays are not captured for a full-screen window, the window ends up at the
same window level as the status items, and they would sometimes end up on top.
They would draw over the full-screen window and could be clicked.
