Rounding the scroll deltas from trackpads causes jerky scrolling behavior
by artificially amplifying the effects of very small scroll movements.
We should only round events from devices with discrete scroll wheels,
because we know the smallest unit of movement there is a single tick.
macOS 10.6 has some touch NSEvents which do not have a subtype
(Begin/EndGesture, Magnify, Rotate, Swipe) and cause an uncaught
exception which triggers SIGABRT and the program exits.
As it is, none of the macOS 10.6 touch events are detected as a
trackpad (including Gesture due to using different subtypes).
This fixes a specific issue seen on macOS 10.14.6 where a DELL E248WFP
Display connected to a 2014 Mac Mini with a scaled 1920x1080 resolution
selected and SDL_Init(SDL_INIT_VIDEO) failed with the error: "The video
driver did not add any displays".
The underlying cause was that the current 1080p display mode did not
have the flag kDisplayModeSafeFlag, the check for which was added in
a963e36, with the idea that certain display modes should not be
candidates for switching to in fullscreen exclusive mode. That may well
be the right thing to do for filtering down a list of candidate modes,
but it doesn't pay to be so picky about the current mode. After all,
this current mode was set by System Preferences, the picture does appear
correctly on screen, and other non-SDL based applications launch and run
correctly in this mode.
Therefore the fix is to have GetDisplayMode only filter out a mode based
on flags if it's part of a candidate list, but if it's the current mode
and it can possibly be converted to an SDL_DisplayMode, do so.
When possible use native os functions to make a blocking call waiting for
an incoming event. Previous behavior was to continuously poll the event
queue with a small delay between each poll.
The blocking call uses a new optional video driver event,
WaitEventTimeout, if available. It is called only if an window
already shown is available. If present the window is designated
using the variable wakeup_window to receive a wakeup event if
needed.
The WaitEventTimeout function accept a timeout parameter. If
positive the call will wait for an event or return if the timeout
expired without any event. If the timeout is zero it will
implement a polling behavior. If the timeout is negative the
function will block indefinetely waiting for an event.
To let the main thread sees events sent form a different thread
a "wake-up" signal is sent to the main thread if the main thread
is in a blocking state. The wake-up event is sent to the designated
wakeup_window if present.
The wake-up event is sent only if the PushEvent call is coming
from a different thread. Before sending the wake-up event
the ID of the thread making the blocking call is saved using the
variable blocking_thread_id and it is compared to the current
thread's id to decide if the wake-up event should be sent.
Two new optional video device methods are introduced:
WaitEventTimeout
SendWakeupEvent
in addition the mutex
wakeup_lock
which is defined and initialized but only for the drivers supporting the
methods above.
If the methods are not present the system behaves as previously
performing a periodic polling of the events queue.
The blocking call is disabled if a joystick or sensor is detected
and falls back to previous behavior.
These would accidentally get a titlebar because the "borderless" style mask
is zero but the resizable attribute adds a bit. I assume this happens because
you used to need window decoration to resize a window in macOS, but this
changed in later releases.
This only caused problems when recreating a window (you had an
SDL_WINDOW_OPENGL window and tried to create a Metal SDL_Renderer on it, etc).
Fixes#4324.
It doesn't appear to work anymore, and was disabled by default anyhow, since
the needed APIs are forbidden on the Mac App Store.
A better solution to lock the mouse to the window on macOS would still be
welcome. CGAssociateMouseAndMouseCursorPosition() works fine for relative
mouse mode, this was just a question of SDL_SetWindowGrab(). As it stands
now, a grabbed mouse can briefly break out of the window, causing varying
degrees of chaos.
- Only focus a new window when one closes if the window that was closed was an SDL window
- If the application already has a key window set that is not an SDL window, don't replace it when the application is activated
- Only register the URL event handler when SDLAppDelegate is going to be set as the applications app delegate. This is to
be consistent with previous behavior that would only register the handler in -[SDLAppDelegate applicationDidFinishLaunching:]
and allows the running app to opt out of the behavior by setting its own app delegate.
- The URL event handler is now removed if it was set on SDLAppDelegate dealloc

If you pass the C string directly to NSLog(), it will be garbled with Japanese and probably other language strings, or no log will be output at all.
NSLog("Hello, World!"); // => "Hello, World!"
NSLog("こんにちは、世界！"); // => No output...
Therefore, you need to convert the string to an NSString before passing it to NSLog().
NSString *str = [NSString stringWithUTF8String:"こんにちは、世界！"];
NSLog(@"%@", str); // => "こんにちは、世界！"
Thank you.
This adds SDL_SetWindowKeyboardGrab(), SDL_GetWindowKeyboardGrab(),
SDL_SetWindowMouseGrab(), SDL_GetWindowMouseGrab(), and new
SDL_WINDOW_KEYBOARD_GRABBED flag. It also updates the test harness to exercise
this functionality and makes a minor fix to X11 that I missed in
https://hg.libsdl.org/SDL/rev/02a2d609369b
To fit in with this new support, SDL_WINDOW_INPUT_CAPTURE has been renamed to
SDL_WINDOW_MOUSE_CAPTURE with the old name remaining as an alias for backwards
compatibility with older code.

Exult (http://exult.info) has an editor app that uses GTK+2. Up to now we were using X's drag'n'drop to allow dropping of assets from the editor onto Exult.
There is now an experimental branch that makes use of SDL_DROPFILE. That works under X, dropping in Exult's SDL2 window puts the asset right at the spot you dropped at.
On macOS with native Exult and Quartz GTK+2 this doesn't work, the location of the drop is where the mouse was last tracked before you left the window (usually one of the edges, unless you tabbed out).
All we tried out pointed to the fact that the location update needs to be done by the dropfile event in SDL2, not by our own (which always only worked after the Exult window getting focus).
This patch adds this to SDL_cocoawindow.m and it works perfectly, passing the correct coordinates to our code (SDL_GetMouseState()).

For a window created with SDL_WINDOW_ALLOW_HIGHDPI, SDL_GL_GetDrawableSize will return the high-dpi drawable size even before any GL context creation happens. But SDL_Metal_GetDrawableSize will return the size of the window if the Metal view has not been created. This is confusing and inconsistent behavior.
An easy way to test this is to build testgl2 and testvulkan on macOS with the SDL_WINDOW_ALLOW_HIGHDPI flag enabled during window creation. The GL2 program will report a drawable size of 2x window width and 2x window height, while the Vulkan program will report the window size.
This patch addresses the issue by falling back to using the content view dimensions if no Metal view exists in the window. (The code for this was taken directly from Cocoa_GL_GetDrawableSize.) With this change, the testvulkan behavior matches that of testgl2.
Note that I haven't tested for this issue on UIKit. It's possible a similar change will need to be made there too.

isOperatingSystemAtLeastVersion is an 10.10 thing.
