the NSWindowButton enum was moved to be a member of NSWindow and renamed
to ButtonType in SDK 10.13. apparently that wasn't documented anywhere.
not even in the SDK changes Document and the official Documentations
makes it look like it was always like this. the old NSWindowButton enum
though is still around on SDK 10.13 or at least got a typealias. so we
will just use that.
when resizing async it's possible that the layer, and the underlying gl
surface, is stretched on an aspect ratio change. to prevent that we do
an atomic resize (resize and draw at the same time). usually max one
unique frame should be dropped but it's possible, depending on the
performance, that more are dropped.
the title bar is now within the window bounds instead of outside. same
as QuickTime Player. it supports several standard styles, two dark and
two light ones. additionally we have properly rounded corners now and
the borderless window also has the proper window shadow.
Also make the earliest supported macOS version 10.10.

even though the fullscreen animation has a shorter duration than the
system wide animation (space sliding effect) there are still cases where
it takes longer, eg performance issues (especially on init). furthermore
the final size of the animation is usually different than the actual
fullscreen size because of spect ratio differences. the actual resize to
fullscreen is done automatically by cocoa itself when the actual
transition to fullscreen happens (system event). so it could happen that
the last animation resize happened after the actual resize to fullscreen
leading to a wrongly sized frame after entering fullscreen. to prevent
this we cancel the animation when entering fullscreen, we always set the
proper frame size when in fullscreen and discard any other frame sizes,
and to prevent some performance problems on init we push entering
fullscreen to the end of the main queue to execute it when most of the
init routines are done.
Fixes#5525
on live resize, eg async resize, the layer's bounds size is not in sync
with the actual surface size. this led to a wrongly sized frame and a
perceived flicker. get and use the actual surface size instead.
drawing off-screen failed because we didn't have a valid context. the
problem is we force off-screen drawing because the CAOpenGLLayer refuses
to draw anything while being off-screen. set the current context before
starting to draw anything off-screen.
Fixes#5530
this is meant to replace the old and not properly working vo_gpu/opengl
cocoa backend in the future. the problems are various shortcomings of
Apple's opengl implementation and buggy behaviour in certain
circumstances that couldn't be properly worked around. there are also
certain regressions on newer macOS versions from 10.11 onwards.
- awful opengl performance with a none layer backed context
- huge amount of dropped frames with an early context flush
- flickering of system elements like the dock or volume indicator
- double buffering not properly working with a none layer backed context
- bad performance in fullscreen because of system optimisations
all the problems were caused by using a normal opengl context, that
seems somewhat abandoned by apple, and are fixed by using a layer backed
opengl context instead. problems that couldn't be fixed could be
properly worked around.
this has all features our old backend has sans the wid embedding,
the possibility to disable the automatic GPU switching and taking
screenshots of the window content. the first was deemed unnecessary by
me for now, since i just use the libmpv API that others can use anyway.
second is technically not possible atm because we have to pre-allocate
our opengl context at a time the config isn't read yet, so we can't get
the needed property. third one is a bit tricky because of deadlocking
and it needed to be in sync, hopefully i can work around that in the
future.
this also has at least one additional feature or eye-candy. a properly
working fullscreen animation with the native fs. also since this is a
direct port of the old backend of the parts that could be used, though
with adaptions and improvements, this looks a lot cleaner and easier to
understand.
some credit goes to @pigoz for the initial swift build support which
i could improve upon.
