This change alters the small square dot cursor to a more visible 16x16
cursor for X11. A new option `spice:largeDotCursor` can be set to use an
alternative 32x32 cursor for the vision impaired.
This commit adds an interface to the X11 display server code to support
various window manage specific features, such as in this case, the i3
global full screen toggle.
This feature specifically uses the i3 IPC to cause looking glass to go
full screen across all monitors if the new option `i3:globalFullScreen`
is enabled.
If the cursor was grabbed the window the cursor moves over when it is
ungrabbed will recieve an EnterNotify event with the mode of
NotifyUngrab, unfortunatly some window manages such as i3 will ignore
this message and as such focus follows mouse will not function
correctly. This patch injects a normal EnterNotify to work around this
issue.
This fixes an issue where the window position would be ignored if the
application was launched in full screen mode from the command line
causing the client to enter full screen on the wrong monitor in
multi-monitor configurations.
Many X11 window managers will present an application on their
taskbar as a combination of the application name and an icon
imagery pulled from the X-Property _NET_WM_ICON. Applications
built under frameworks such as Qt or GTK have this property
populated by the framework. This commit adds the Atom _NET_WM_ICON
and populates it with a 64x64 icon of Looking Glass.
For an unknwon reason when LG is on another desktop (hidden) and the
user switches to that desktop, the first attempt to grab the pointer
results in a GrabFrozen result. This adds some simple retry logic to
attempt again after a short (100ms) delay which seems to resolve the
issue.
The Linux OpenGL ABI does not guarantee that glXSwapIntervalEXT will be
exported statically from any library, and indeed on some systems this
function does not link at load time, e.g. with amdgpu-pro. All other
GLX functions that we use are from GLX 1.0, which is guaranteed to be
exported statically.
This commit solves this issue by using glXGetProcAddressARB to load the
function. Note that only the ARB version of glXGetProcAddress is
guaranteed to exist by the Linux OpenGL ABI, which is why we must use
it.
External events like launching other applications can cause latency
spikes while X11 initializes the application, we should only start
adjusting our delay if we see excessive skips over a 1s period.
Invalidating the entire window on an Expose event causes poor WM
performance when dragging the window around. Instead flag to redraw and
wait for the expose events to stop for 100ms before doing it.
