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.

203ebc73eb [client] x11/opengl: enable double buffering for OpenGL
Drawing to the front buffer directly requires special handling to
prevent seeing the draw progress (avoiding glClear, etc) and as a result

enabled will not function without double buffering enabled.

As OpenGL is the legacy fallback, there are no plans to implement clean
front buffer draw support, so just enable double buffering.

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.

71c9680245 [client] wayland: use locked pointer to implement capture mode

The XInput2 specification is light on details, but "Rel X" and "Rel Y"

6b26089353 [client] wayland: keep track of wl_output scale information
This will later be used to control the size of the underlying EGL buffers
in order to handle high DPI.

5649d1ad95 [client] wayland: split Wayland display server into modules
The Wayland display server is getting unwieldy due to the sheer size.
To make it easier to edit in the future, I split it into many components
based on logical boundaries.

1ba1108099 [client] wayland: add option to enable cursor warp
This is enabled on default. Specify wayland:warpSupport=no to disable it,
which may be useful on certain compositors that do not warp when the
pointer is confined.

9b688909b0 [client] wayland: support LG_DS_WARP_SURFACE
This commit implements support for LG_DS_WARP_SURFACE, as well as a warp
routine based on cursor confines.

This may not necessarily work for all compositors. As such, the old cursor
routines are still kept, and used when wm.warpSupport is set to false.

270631f1b9 [client] ds: add surface-only warp variant
This commit converts the output of ds->getProp(LG_DS_WARP_SUPPORT) to
an enum containing three items:

* LG_DS_WARP_NONE: warp is not supported at all
* LG_DS_WARP_SURFACE: warp is possible, but only inside the window
* LG_DS_WARP_SCREEN: warp is possible anywhere on the screen

LG_DS_WARP_NONE corresponds to the old false return value, and
LG_DS_WARP_SCREEN corresponds to the old true return value.

LG_DS_WARP_SURFACE is designed for Wayland, where warping is possible,
but only in our window. In this case, since we cannot warp outside
the window, we can warp the cursor to the edge when we attempt to exit.
If the cursor leaves, the normal leave routine gets called, and the
cursor disappears. If the cursor does not end up leaving, we grab it
again.

This allows multiple Wayland clients to stream data from looking glass
without blocking the looking glass main thread.

a450e0f8f5 [client] wayland: better self-copy detection
This new implementation uses a special mimetype to tag data copied from
the guest, instead of using flags. This should make it easier to
implement asynchronous transfers in the future. Also, it's simpler to
understand and less error-prone.

The pid is included in the mimetype in order to distinguish between
different instances of looking glass: you might want to copy between
two different VMs, for example.

cc2104c699 [client] wayland: cleanup surface and display
These used to be owned by SDL and can't be cleaned up. This has since
changed.
