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.

This is so negative coordinates are adjusted in the same direction as
positive ones (left and up).

Cocoa manages an autorelease pool on the main thread, but it only drains it
when it processes an event. Our requests come through a run loop source, which
doesn't count as an event. So, autoreleased objects can accumulate when the
app is not being interacted with.

Commit 793ab7d45 fixed a bug where WINDOW_BROUGHT_FORWARD events weren't being
posted when they should, but it caused a regression in Scribblenauts Unlimited.
Every click caused a window ordering operation that generated messages and
Scribblenauts would move the mouse cursor to the upper-left corner of the
window in response.

Not sending the brought-forward event for a click that was sent was an artifact
of a time when that branch was only used for posting a request for focus. When
I added the brought-forward event, I didn't reconsider that logic.
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.
When a window is being dragged, we prevent delivery of clicks to Wine. We were
also preventing telling Wine that a window had been brought forward, but this
was incorrect. It prevented clicks in the title bar from activating the window.
If the mouse is captured, we change which window receives the click event, but
that shouldn't change which window we tell Wine was brought forward by Cocoa.
We can't prevent Cocoa from bringing disabled/no-activate windows forward. So,
we need to tell Wine about the z-order change.
We still do avoid telling Wine to activate disabled/no-activate windows, though.
The Mac driver can generate scroll wheel events with values which are not integral
multiples of WHEEL_DELTA. Apps should handle that by scrolling a corresponding
non-integral multiple of what they'd do for a WHEEL_DELTA-valued scroll or, if
they can't, then at least accumulate scroll distance until its magnitude exceeds
WHEEL_DELTA and do a "chunky" scroll. However, many apps don't do that properly.
They may scroll way too far/fast or even in the opposite direction.
If the registry setting UsePreciseScrolling is set to "n", the Mac driver will do
that accumulation and chunking itself to work around such broken app behavior.
Cocoa will bring an unowned window to the front of its level when it's clicked,
but it doesn't do that for owned windows. The old code went out of its way to
make owned windows behave like unowned windows in this respect. That was
exactly backward. We wish we could control whether windows are raised on a
click. We don't have that opportunity for unowned windows, but, by ripping
out a bunch of code, we do for owned windows.
Many games clip the cursor to the client area of the window. However, on OS X,
the resizing controls extend into that client area. So, it's possible that
while playing, the user might unintentionally click in the resizing area and
drag, resizing the window.
We only care if we have changed the mode and we're changing it back to its
original. Even if the current mode matches the target mode, we may still
need to release the displays and clear the entry from originalDisplayModes.
originalDisplayModes should be used when active, empty when inactive.
latentDisplayModes is used when inactive, empty when active.
The count of entries in originalDisplayModes is used to test whether the
process has the displays captured so adding entries when inactive would give
incorrect results. This could have led us to mistakenly change the display
mode when we don't have the displays captured.
Among other things, this fixes Syberia 2. That game shows, hides, and then
shows its window. Hiding it caused a WINDOW_LOST_FOCUS event to be queued.
By the time it was processed, the window was the foreground window again.
In response to being told it had lost focus, the game minimized its window.
Hiding the window should have prevented or discarded the WINDOW_LOST_FOCUS
event since the change was driven from Wine and the Win32 foreground/active
window state would already be correct. In addition, when the program
re-showed its window and made it foreground, that should have discarded the
event as being out of date. Now they do.
Fixes a problem in some games which repeatedly (re)establish the same cursor
clipping rect, making it exceedingly difficult to move the camera with the
mouse.
This simulates some of what would happen if user32 were managing the drag. The
click in the caption would cause WM_SYSCOMMAND/SC_MOVE. The processing of that
message is synchronous and doesn't return until the move is complete.
Some games require that "blocking" in the internal event loop to prevent them
from misbehaving during the drag.
The tracking of whether it is over a window or not is only updated when the
mouse moves. If a window was created or moved under it, then the state can be
stale. That caused us to defer hiding the cursor until the mouse was moved.
This happens at the start of games pretty often.
The code had previously set the cursor back to the standard arrow and unhid
it when it left all app windows. Now it restores the cursor image that the
app set and re-hides it if necessary when it moves back over any app window.
Cocoa would automatically do this for a normal app. However, the Mac driver
makes all of its windows inherit from NSPanel and Cocoa ignores panels for
this feature.
The Mac driver captures the displays when the program changes the display
mode. If the user types Command-Tab to switch away, it resets the displays
to their original modes and releases them. However, if they switched back,
it didn't restore the mode to what the program had set, so the program often
showed the game window in a corner of the screen with the top behind the Mac
menu bar.
Cocoa won't order a minimized window out of the screen list using -orderOut:.
This leaves a window that should be hidden still visible in the Dock, where
it can be unminimized.
This matches what Cocoa does when determining how to handle an event so that,
for example, our test if a click is in the window grow box corresponds to
whether Cocoa will run an internal mouse-tracking loop to resize the window
when we pass it the event. This fixes a problem where both Cocoa and user32
would try to run a resize loop and the cursor would get "stuck" resizing the
window after the button was released.
It may be necessary to reorder to some extent because the clicked window is
behind a sibling at the same level, but that shouldn't move it later in the
list than higher-level siblings.
Cocoa gets buggy if the list of child windows isn't in z-order.
The right place may not be the end of the list of Cocoa child windows if some
of the siblings are at a higher window level (i.e. floating if the clicked
window is not).
For keys pressed in combination with Command, -[NSApplication sendEvent:]
simply doesn't pass the key-up event through to the window. We have to
track which keys we've told Wine are pressed because Cocoa may consume
key-downs that trigger menus or system behaviors.
