908aa84599 [client] wayland: use acceleration in capture mode unless rawMouse
We are forced to use accelerated movement in regular mode as that is how the
host machine cursor moves and we want the cursors to line up (since Wayland
cannot do warps). To avoid a change in sensitivity when toggling capture
mode on/off, we should use accelerated deltas for capture mode as well,
unless the user explicitly asks for raw input with input:rawMouse.

6077dcc123 [client] spice/wayland: fix jitter when moving the cursor slowly
It does not make sense to accumulate fractional error in non-capture mode
as you know exactly where the cursor is supposed to be, at least on Wayland.

On Wayland, we base movements on the current guest position and desired
target position, and the accumulated errors only skew our movements.

f86800cc3a [client] mouse: process mouse up event even if not in view
Unless the corresponding mouse down event was on our surface, we should
not be receiving the mouse up.

This is always the case on Wayland. On some other platforms,
SDL_CaptureMouse can be used to obtain input that happens outside the
Looking Glass surface, but Looking Glass does not make use of that
function.

We may want to process a mouse up if the corresponding mouse down
initiated a drag (e.g., of a window) that was released slightly outside
of the Looking Glass surface. Previously, Looking Glass would ignore the
mouse up, and the guest would be confused into thinking the button had
never been released, not ending the drag.

Some users also run software in one-off nested compositors like cage[0]
for an extra layer of isolation; cage, at least, does not support
pointer captures.

This commit makes Looking Glass warn when an optional protocol is
unsupported, and fail if a required one is missing. Pointer grab paths
have a new guard against the aforementioned protocols being missing.

078a151e4f [client] wayland: update absolute mouse position
We are actually getting mouse events directly from Wayland instead of going
through SDL, so we call app_updateCursorPos in pointer motion handlers and
swallow the SDL event.

Also removed parameters for app_handleMouseBasic as it relies exclusively on
absolute positions provided by app_updateCursorPos. Wayland does not give
you relative movements at all unless grabbed and passing absolute movements
is semantically incorrect.

Note that when the cursor is grabbed, movements are handled entirely through
relativePointerMotionHandler in wayland.c and does not go through
app_handleMouseBasic at all.

0495f5de26 [client] enable useful extra warnings
-Wno-sign-compare is used to suppress warnings related to comparing signed
values with unsigned ones. It's too pedantic.

-Wunused-parameter is also too pedantic, especially since all parameters
have to be named in C.

Otherwise, -Wextra lets us catch bugs, such as x < 0 for unsigned x.

On gcc, we pass -Wimplicit-fallthrough=2 so it will recognize our fall
through comment.

a46a3a2668 [all] use explicit void parameter lists
This makes it a compile-time error to call a function that semantically
takes no parameters with a nonzero number of arguments.

Previously, such code would still compile, but risk blowing up the stack
if a compiler chose to use something other than caller-cleanup calling
conventions.

17691f889b [client] clipboard/wayland: avoid writing back to guest clipboard
Copying rich text from the guest would be turned into plaintext on the client.
Prior to this change, this would be sent back to the guest, overwriting its
clipboard. This made it impossible to copy rich text inside the guest.

This commit detects such self-copies by checking if the receiver is the
current process, and rejecting it.

On Wayland, SDL_WINDOWEVENT_CLOSE is sent even when exiting with keyboard

We now swallow SDL_WINDOWEVENT_CLOSE if the cursor is inside the VM. This
should prevent keyboard shortcuts from closing the client, while still
allowing the window to be closed by clicking X with the mouse per #138.

of the warp by matching the target x/y.

The old code also had an error where it would null out any additional
movement since the warp was requested, but before it was processed, this
has been corrected.

As X11 is a server/client protocol, issuing commands such as
XWarpPointer do not happen immediately, as such we need to identify when
the warp is complete to know to null out the movement. To do this we
track each warp issued and look for it's completion in the event filter.
As some events come in via XInput2 we need to also make use of this
instead of just relying on MotionNotify, as such the support has been
implemented for XI_Motion events.

523accf348 [client] spice: don't rely on the cursor position when it's not visible
DXGI DesktopDuplication does not send cursor positional updates when the
cursor is hidden, this happens when dragging a window around or when a
full screen application takes/hides the cursor. If this happened at the
same time as a resolution switch we don't know where the cursor really
is anymore.

d997f0d18c [client] spice: properly handle high-precision scroll wheel input
Some setups (e.g. Wayland) have high precision scroll wheel input, such
that the y-delta on an event may exceed 1. In these cases, scrolling up
currently gets treated as scrolling down.

This commit changes the checks to use > 0 rather than == 1.

This is the approach suggested in
https://wiki.libsdl.org/SDL_MouseWheelEvent.

1ca5e439c1 [client] egl: disable EGL when running on Wayland
This commit makes Looking Glass always use the OpenGL renderer when
running on Wayland. The EGL renderer is broken on Wayland and can't
reasonably be fixed until SDL is dropped entirely (as per
https://github.com/gnif/LookingGlass/issues/306).

Until that time, the OpenGL renderer provides a much better
Wayland-native experience.

4bceaf5505 [client] fix hang in eglSwapBuffers when exiting while not visible
eglSwapBuffers is allowed to block when called with a nonzero interval
parameter. On Wayland, Mesa will block until a frame callback arrives.
If an application is not visible, a compositor is free to not schedule
frame callbacks (in order to save CPU time rendering something that is
entirely invisible).

Currently, starting Looking Glass from a terminal, hiding it
entirely, and sending ^C will cause Looking Glass to hang joining the
render thread until the window is made visible again.

Calling eglDestroySurface is insufficient to unblock eglSwapBuffers, as
it attempts to grab the same underlying mutex.

Instead, this commit makes it so that we pass a 0 interval to
eglSwapBuffers when running on Wayland, such that we don't block waiting
for a frame callback. This is not entirely ideal as it *does* mean
Looking Glass submits buffers while hidden, but it seems better than
hanging on exit.

It also forces opengl:vsync and egl:vsync flags to off when running on
Wayland, as they are meaningless there.

e31f38eadc [client] allow frame updates to be triggered by a timed event
This is a major change to how the LG client performs it's updates. In
the past LG would operate a fixed FPS regardless of incoming update
speed and/or frequency. This change allows LG to dynamically increase
it's FPS in order to better sync with the guest as it's rate changes.

cc2c49644d [spice] reworked to avoid locking requirements on the input channel
POSIX `send` is thread safe, to take advantage of this the code has been
changed to construct a contiguous buffer and perform the send in a
single operation preventing any risk of a race condition.

Only the main channel still requires an interlock as the VD agent
requires multiple sends to transmit a full buffer.

to correctly track the window size. Since we are not that intertested in
touch for our usecase, we just turn the events off again.

70110b4a5a [client] Use eglGetPlatformDisplay() to fix surface creation
[Why]
Recent versions of Mesa may have trouble with surface creation, resulting in
errors like:
egl.c:428  | egl_render_startup             | Failed to create EGL surface (eglError: 0x300b)

[How]
Replace eglGetDisplay() with eglGetPlatformDisplay(). Requires EGL 1.5, but should
be supported with any desktop driver released in the past few years.

bca54ab1f6 [client/host] added new asyncronous memory copy
This changes the method of the memory copy from the host application to
the guest. Instead of performing a full copy from the capture device
into shared memory, and then flagging the new frame, we instead set a
write pointer, flag the client that there is a new frame and then copy
in chunks of 1024 bytes until the entire frame is copied. The client
upon seeing the new frame flag begins to poll at high frequency the
write pointer and upon each update copies as much as it can into the
texture.

This should improve latency but also slightly increase CPU usage on the
client due to the high frequency polling.
