0a7c1ff21c lib: use mouse-set from peer to update local position
We may need to tweak this for relative mouse positions if we find we dont
get reliable information from the peer. But this is a start, which I see
we get back from Qemu at least when we're in -enable-kvm mode.

7c63e051fd lib: use legacy event controller
Now that we are doing our own paintable management, we can more easily
transition to doing our own event management with the Legacy event
controller (which, despite the name, really just allows us to get more
direct GdkEvent for processing).

Additionally, this adds support for scroll events to the guest.

eb32afc2a9 lib: add util to check for inverted scroll
This has limited functionality because what we really need is support for
wayland!183 as it would only work unsandboxed.

But it provides a convenient abstraction point for implementing that as
well once we have it.

This is mostly useful so that we can see things within the inspector at

a8505e1245 lib: remove use of GtkPicture
We want a bit more control over things than we can get with GtkPicture so
do the snapshot/measure internally. This allows us to know where the
picture is to be allocated so that we can translate pointer events to the
location within the console.

2e842f7e7f lib: add GdkDmabufPaintable
This just starts on the DMA-BUF code and abstracts MksPaintable so it can
encapsulate both MksDmabufPaintable and MksCairoFramebuffer.

Currently, the dmabuf just tailes everything (fully) but we can fix that
with snapshot work stil. Either way, want to get the abstraction landed
first before we dive deeper into that.

These come out to 64kb with 4 bytes-per-pixel which seams reasonable

6c5829d949 lib: make clicks and motion work
We need to handle a mouse that is not absolute positioned (the default it
seems) and this does that (crudely for the moment until we have some sort
of grab management).

Additionally, click events are propagated to the Qemu instance as well.

ddd6a58adc lib: use g_variant_get_data_as_bytes() to get byte array
We don't want to go through get_bytestring() as this is a bit cleaner as
to ensure we're holding onto references for the rest of the function
lifetime. Otherwise, completing the operation could cause our parameters
to be released (at least theoretically).

6beaf8b925 lib: encapsulate GtkPicture within MksDisplay
We don't need to do this manually now that we have GtkPicture working
correctly with content-fit. We still want to maintain our own widget to
manage things like grabs and all that though.

01dab99590 lib: add MksCairoFramebuffer
This adds MksCairoFramebuffer which does tessellation to get damage regions
for the framebuffer. Still some bugs involved, but good enough to get some
bits on the screen which is what I'm looking for right now.

56e9997919 lib: connect asynchronously to socketpair peer
Because the other side is doing AUTHENTICATION_SERVER, which really it
has no business doing any flags, we have to connect asynchronously or we'd
block because it doesn't yet have our FD to communicate with.

So connect asynchronously, return our FD, and then process from there.

This is somewhat annoying because it means you can't connect your
object until the otherside already sees our connection. We delay message
processing to help with that though.

ed03ea5148 lib: move PaintableListener into MksPaintable
The goal here is to keep the MksPaintableListener inside of MksPaintable
so that we don't have to create API between the two. Additionally, the
MksPaintable can own it's own G-DBus connection as we don't want to share
them for updates with anything else (as they can have large data chunks
coming across).

07158dfa07 lib: add a framebuffer paintable
This is intended to be the software fallback path where we have to take
Update() and Scanout() method invocations from the Qemu instance. It
implements paintable and tries to reuse a backing texture until a threshold
has been met at which point it does a full redraw.

The backing texture is reused between snapshots to increase the chance that
we may skip a followup VRAM upload to the GPU. The damage rectangles will
be re-uploaded each frame. There is some opportunity to optimize that
last part by keeping them around and adding a secondary damage region.

Of course, we would still want things to go the MksDmabufTexture path
when possible.

629cfd0e28 lib: add mks_screen_attach()
This is ultimately going to give us back a paintable, but it's only in
partial state right now. We need to figure out the right semantics for
ownership between the listener/paintable/screen/etc.

We may want the widget to be the owner of everything (and keep the
painable/listener internal API) which is likely the most convenient from
an object ownership standpoint.

5e75216318 lib: stub internal listener skeleton
This is an org.qemu.Listener using the gdbus-codegen generated skeleton as
the parent type.

What will probably happen here, is that we create a MksPaintable which is
given to the listener to call internal API upon.

The paintable code will be a bit more complex than originally anticipated
in that we are going to need to do our own tessellation so that we get
damage regions which are not the whole widget. Very similar to what I did
in the GdkMacosTile for gdk/macos/.

9bb71b8ea8 lib: add MksScreenAttributes and mks_screen_configure()
MksScreenAttributes is an opaque type with setters so that we can
potentially extend it in the future without ABI issues.

Furthermore, this adds a configure API for both sync and async to
MksScreen.

Currently, I get NOT_SUPPORTED back from Qemu, but I think that's because
I'm not even past the bootloader/EFI stage for tests.
