Previously, the popover would cause the window to go into the :backdrop
state which is not what we want for consistency with other platforms. This
fixes that by walking up the surface chain when we get notified of
loosing or acquiring "key" input from the display server.
One may be using IJG libjpeg or libjpeg-turbo to build GTK, and their
build files may or may not generate pkg-config files for us. To make
things easier, we can make use of CMake's built-in support for finding
IJG libjpeg or libjpeg-turbo.
The CMake build files for libtiff may or may not generate pkg-config
files for us, so we can use Meson's CMake support to help us find
libtiff, as CMake has built-in support for finding libtiff.
Add a variable in meson.build that covers Visual Studio-like compilers,
so that we can use it to help us find depedencies using CMake rather
than via pkg-config, where applicable.
Change the existing use case for finding libpng accordingly.
This significantly cleans up how we handle various move-resize, compute-
size, and configure (notification of changes) in the macOS GDK backend.
Originally when prototyping this backend, there were some bits that came
over from the quartz backend and some bits which did not. It got confusing
and so this makes an attempt to knock down all that technical debt.
It is much simpler now in that the GdkMacosSurface makes requests of the
GdkMacosWindow, and the GdkMacosWindow notifies the GdkMacosSurface of
changes that happen.
User resizes are delayed until the next compute-size so that we are much
closer to the layout phase, reducing chances for in-between frames.
This also improves the situation of leaving maximized state so that a
grab and drag feels like you'd expect on other platforms.
I removed the opacity hack we had in before, because that is all coming
out anyway and it's a bit obnoxious to maintain through the async flows
here.
If we have GStreamer on macOS we likely have support for CGL to get an
OpenGL context we can use. This provides the missing pieces to get
accelerated video playback in gtk4-widget-factory working.
We want our tracking area to be limited to the input region so that we
don't pass along events outside of them for the window. This improves the
chances we click-out of a popover with a large shadow.
This still doesn't let us pass-through clicks for large shadows on top-
level windows though.
We only should be asserting in static functions. Furthermore, this function
did not need to have GDK_BEGIN_MACOS_ALLOC_POOL as nothing is being
allocated there which would cause pooling to get used.
This needs to handle the boundary case where the value is exactly equal
to the edge of a rectangle (which gdk_rectangle_contains_point() does not
consider to be containing). However, if there is a monitor in the list
that is a better match, we still want to prefer it.
When using an external mouse on MacOS, the scrolling behavior is
reversed from the user's scrolling preference. Additionally, it is
noticeably sluggish.
This commit fixes both issues by negating the deltas and multiplying
them by 32 before constructing a new scroll event. 32 seems to be the
"traditional" scaling factor according to [Druid], but I'm not sure
where that value actually comes from. Regardless, scaling the deltas by
this amount makes scrolling feel a lot more responsive in the GTK demos.
Scrolling with a trackpad is not affected by either issue because it
triggers a different code path that uses more precise deltas, and
already negates them.

This was causing us to draw the same background content twice which is a
significant amount of bits to flip in the GPU for maximized windows,
especially twice.
