60ac03ebaf [client] wayland: implement window size setting for xdg-shell
This should allow win:autoResize to work on Wayland when the compositor
supports such an operation.

0ad469178a [client] wayland: make it possible to disable fractional scaling
The method used is not guaranteed to work on all Wayland compositors,
so offer a way out. We need to support it anyways in case xdg_output
or wp_viewporter protocols are not available.

b3ca872cef [client] wayland: improve fractional scale handling
Currently, we scale the desktop up to the next largest integer, and rely on
the wayland compositor to scale it back down to the correct size.
This is obviously undesirable.

In this commit, we attempt to detect the actual fractional scaling by finding
the current active mode in wl_output, and dividing it by the logical screen
size reported by xdg_output, taking into consideration screen rotation.

We then use wp_viewporter to set the exact buffer and viewport sizes if
fractional scaling is needed.

0cbc529640 [client] ds: refactor common EGL swap with damage logic
This commit creates a new utility library, eglutil.h, which contains code
to detect and use EGL_KHR_swap_buffers_with_damage or its EXT equivalent.

This logic used to be duplicated between the X11 and Wayland display servers,
which is not ideal.

7f5f46c448 [client] wayland: offer all supported clipboard formats
This commit restructures the Wayland clipboard handling for host->VM.

Before, we select one clipboard format and buffers the data for it, to
be presented to spice when needed.

Now, we simply offer all clipboard formats supported, and only when spice
asks for the data do we actually read the wl_data_offer. The wl_data_offer
is kept around until a new offer is presented, the offer invalidated, or
when we lose keyboard focus. This is in accordance with the specification
for wl_data_device::selection, which states that:

> The data_offer is valid until a new data_offer or NULL is received or
> until the client loses keyboard focus. The client must destroy the
> previous selection data_offer, if any, upon receiving this event.

We still buffer the entire clipboard data into memory because we have no
knowledge of the clipboard data size in advance and cannot do incremental
transfers.

Furthermore, if the user performs drag-and-drop on our window, we may have
need to handle multiple wl_data_offer objects at the same time. Therefore,
instead of storing state on the global wlCb object, we instead allocate
memory and store it as user_data on the wl_data_offer. As a result, we also
handle drag-and-drop so that we can free the memory.

e70cfd84fb [client] egl: use eglSwapBuffersWithDamageKHR for cursor-only updates
Instead of damaging the entire surface when rendering a cursor move,
we can use the EGL_KHR_swap_buffers_with_damage extension to only
damage the part of the window covered by the cursor. This should
reduce the cursor movement latency on Wayland.

0f2fd84724 [client] ds: avoid util_cursorToInt when warping pointer
Using util_cursorToInt messes with the error tracking for normal movements,
and is not necessary since we are computing an absolute position on the
client window.

Instead, we should pass doubles directly to display servers and let them
decide how to best handle them. For example, XIWarpPointer accepts doubles
directly.

71c9680245 [client] wayland: use locked pointer to implement capture mode
This prevents the host cursor from moving into another window in capture
mode, solving the problem of input going to an overlapping window in
capture mode, and also preventing loss of focus with focus_follows_mouse.

00c2773e6b [client] ds: separate grab and capture logic
Currently, (un)grabPointer is used both for tracking/confining the mouse
in normal mode, as well as entering/exiting capture mode. This makes it
impossible to use separate cursor logic for capture mode, which is needed
to deal with overlapping windows for the Wayland backend.

This commit creates separate (un)capturePointer for entering/exiting
capture mode. There should be no behaviour changes.

d0a12f6097 [client] ds: detect when the cursor exits into an overlapping window
This adds a new method to the display server interface to allow the
application to notify the ds when there is a guest cursor position
update along with the translated local guest cursor position. This makes
it possible for the display server to keep the local cursor position in
sync with the guest cursor so that window leave events can be detected
when the cursor would move into an overlapping window.

Wayland currently just has a stub for this, and the X11 implementation
still needs some minor tweaking.

d6b8823dce [client] wayland: gracefully downgrade to wl_output v2
We don't necessarily need `wl_output.release`, which is the only
addition in v3.

This allows Looking Glass to run on Ubuntu 20.04 without having to go
difficult lengths to acquire newer Wayland packages. Since 20.04 is an
LTS release, this seems worthwhile for the small amount of complexity
this introduces.

389d8824e2 [client] wayland: handle output scale changes
If the scale factor of an wl_output changes while the client is running,
the maximum scale factor is not updated. This may result in incorrect

Therefore, when the scale factor is changed, we should generate a
