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.
According to Erik @ NVidia the open source NVidia driver will not
create a EGLImage from a DMABUF if the target is not
GL_TEXTURE_EXTERNAL_OES. This change set converts the dmabuf texture
from GL_TEXTURE_2D to GL_TEXTURE_EXTERNAL_OES and at runtime performs a
global search & replace on fragment shaders as needed to remain
compatible, replacing `sampler2D` with `samplerExternalOES`.

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 a rounding issue on certain hardware (NVidia) which actually
implement mediump as half precision (16-bit) float. It's safe to assume
`highp` is available as if the GPU does not support it, then the shader
compiler will try to find a lower precision that is supported by the GPU
This is rare and I'm not sure what causes it, but PipeWire sometimes uses a
larger period size than requested for no obvious reason (e.g., we could
request a period size of 512, but PipeWire uses 2048 anyway). This causes
us to stay in a permanent state of underrunning because the target latency
is too low.
With this change, we use the actual device period in the target latency
calculation if it is larger than the expected maximum. We may still get
some glitches at the beginning of playback (because the startup latency is
based upon the expected maximum period size), but it will recover after a
few seconds as it adjusts to the new target latency.
This fixes the following crash when attempt to toggle capture at the
right after closing the overlay:
zwp_pointer_constraints_v1@12: error 1: a pointer constraint with a wl_pointer of the same wl_seat is already on this surface
