Ken Thomases 654b27823d winemac: Fix failure to render OpenGL on macOS 10.14 (Mojave).
For programs linked against the macOS 10.14 SDK, Mojave makes all view
hierarchies layer-backed.  For views to which OpenGL contexts have been
attached this caused a regression where they sometimes failed to render and
just remain black.  Updating the OpenGL context after the framework has
assigned a layer to our view works around the problem.  Thanks to Elviss

Ken Thomases b6a4b2f593 winemac: Track whether a view has ever had an OpenGL context attached.
... 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.

Ken Thomases 302593c9c0 winemac: Better handle z-ordering windows that are in Cocoa parent-child window relationships.
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.

Sierra (macOS 10.12) changed the behavior of key repeat.  In previous versions
of macOS, key repeat stops when a modifier key is pressed or released.  In
Sierra, it does not; it just keeps repeating as newly-modified.

On Windows, key repeat stops when a modifier key is pressed, although not when
one is released.  Some programs depend on this behavior.  So, the Mac driver
emulates it.

Ken Thomases a85f11c2e6 winemac: Post WINDOW_FRAME_CHANGED with the non-fullscreen frame when exiting of fullscreen mode begins.
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.

Ken Thomases fdd7db0593 winemac: Set windows to transparent until they have content to draw, to reduce flicker.
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.

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 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.
