This allows us to build with libdecor enabled as the selection to use it
is decided upon at runtime if the compositor `gnome-shell` is detected.
If the libdecor development headers are installed, by default it will
now be compiled in unless overridden by the user at compile time.
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
