48f002992a [client] wayland: fix mouse logic after refactor
Now correctly set inView to only be within the guest and not the letterboxed
areas. Also show the system cursor in the letterboxed area.

72c86d7125 [client] all: add screen rotation support win:rotate
Currently only supports EGL, if there is enough demand for OpenGL
support this can be added later.

78cb65a6a4 [client] spice: correctly use fabs for floating point
The prototype for abs is int abs (int n), which implicitly casts floating
point values to integers. The correct function is fabs.

This commit allows the client to compile under clang.

369c49cdcf [client] render/opengl: remove braces so fallthrough comment is recognized
gcc -Wimplicit-fallthrough only detects comments if they are immediately
preceded before the next label. Braces stops it from recognizing the
fallthrough comment.

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.

dc17492750 [client] clipboard/wayland: make DnD a no-op
Wayland requires us to set all listeners, even for events we don't care
about. Not doing so caused Looking Glass to abort when used as a drop
target.

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.

c9f41ea69e [client] fix ignoreQuit on Wayland
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.

a larger serial instead of an exact match, and confirms the completion
of the warp by matching the target x/y.

9b309db964 [client] spice: general improvements to cursor warp logic
Previously only up to two pending warp requests were possible, this
changes this so that additional warps can be queued if the cursor's
delta has moved more then 50px between each warp request.

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.

6f99280fe3 [client] fix the warp logic to account for still pending warps to finish
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.

3b0a98ede2 [client] spice: use xlib directly for warping
This change allows us to look for and filter out the warp completion

do so. This is far more elegant then the x/y match that we were doing
prior.

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.
