Ken Thomases 9fbc364ea1 winemac: Remove an unnecessary call to -[NSView removeFromSuperview].
It's only obliquely documented, but -[NSView addSubview:positioned:relativeTo:]
will remove the view from its old superview if it's changing superviews.  If
it's just changing z-order within its current superview, it won't.

This avoids some flicker of OpenGL surfaces being removed and re-added.

Ken Thomases d91e568635 winemac: Mirror the hierarchy of Win32 child windows with Cocoa views.
This only really affects OpenGL child windows.  GDI rendering to the window
surface is still only blitted to the window's content view.  The descendant
views don't draw and so are transparent, letting the content view show through.

Using Cocoa views for child windows fixes a problem where changes to the
position and visibility of child GL windows didn't properly affect the Cocoa GL
view.  Hiding, showing, and moving the top-level window affected the Cocoa
window and thus, indirectly, the GL view.  Moving the child GL window itself
was propagated to the GL view, so that worked.  But hiding, showing, or moving
any of the intervening ancestors of the child GL window didn't properly affect
the GL view.  Neither did hiding or showing the child GL window itself.

This also slightly improves the clipping of the GL view by its ancestors,
although it still doesn't work quite right due to Cocoa bugs.  There are also
remaining bugs with z-order among multiple GL views and clipping by overlapping
siblings.  I hope to eventually fix those using Core Animation layers, for
which this is a prerequisite.

Ken Thomases 1c94bf396f winemac: Add support for a high-resolution ("Retina") rendering mode.
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.

Ken Thomases b4fc81bdf2 winemac: Stop the CVDisplayLink when there are no more changes to flush.
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.

Ken Thomases 3beec95a09 winemac: Use CVDisplayLink to limit window redrawing to the display refresh rate.
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.

Ken Thomases dbb0bacf67 winemac: Fix how the user's default display mode is determined.
The code had been checking the kDisplayModeDefaultFlag in the mode's IOFlags,
but that doesn't do what I thought.  That indicates which mode the driver
considers to be the default for the hardware.  It turns out there's no way to
query the user's default mode.

So, at the first opportunity during a given Wine session, the Mac driver
queries the current display mode and assumes that's the user's default mode.
It records that in a volatile registry key for use by subsequent processes
during that same session.

This doesn't use the existing registry key under
HKEY_CURRENT_CONFIG\System\CurrentControlSet\Control\Video that records the
mode when CDS_UPDATEREGISTRY is used with ChangeDisplaySettingsEx() -- which
explorer.exe does during start-up -- because a) that doesn't support the
distinction between pixel size and point size for Retina modes, and b) in
theory, apps could overwrite that.

Ken Thomases 496b001ae0 winemac: Use a snapshot of an owned window when a zero-sized owner window is minimized.
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.

Ken Thomases 9372af77a5 winemac: Queue an event to reassert the WinAPI window position before Cocoa adjusts its position for a display change.
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.

Ken Thomases 47708c2635 winemac: Add a new registry setting, OpenGLSurfaceMode, to control how GL surfaces relate to the window.
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.
