choice ("autovideosink") and the two X11 videosinks "ximagesink" and

autovideosink chooses a different videosink, ZOOMFIX is now ignored. If
you are using the X11 windowing system (standard on Linux), and have
trouble with screen-sharing on Zoom, use ZOOMFIX and "-vs xvimagesink"

As other videosink choices are not affected by ZOOMFIX, they may or may
not be visible to screen-sharing apps. Cairo-based windows created on
Linux with "-vs gtksink" are visible to screen-sharing aps without
ZOOMFIX; windows on macOS created by "-vs glimagesink" (default choice)

1.59 2022-12-10 remove "ZOOMFIX" compile option and make compilation
with X11 dependence (that now provides a toggle into/out of X11
fullscreen mode with the F11 key) the default if X11 development
libraries are detected. (ZOOMFIX is then automatically applied for
GStreamer \< 1.20.) The cmake option -DNO_X11_DEPS now allows
compilation with no X11 dependence. Also reworked internal handling of
metadata.

### ZOOMFIX compile-time option
In GStreamer-1.18.6 and earlier, if UxPlay is using an X11 window for
screen mirroring, this window is not visible to screen-sharing apps like
ZOOM. OpenGL-based windows (use `-vs glimagesink` or `-vs gtksink`,
*etc.*) do not have this problem.
A workaround is to manually make the X11 window visible to
screen-sharing apps with the X11 utility xdotool, if it is installed,
with: `xdotool selectwindow set_window --name <name>` (where `<name>` is
your choice of name), and then select the uxplay window by clicking on
it with the mouse.
However, if "`cmake -DZOOMFIX=ON .`" is run before compiling, the
mirrored window is visible to screen-sharing applications, without this
procedure. To compile with ZOOMFIX=ON, the X11 development libraries
must be installed. (Without ZOOMFIX, UxPlay has no dependence on X11).
**ZOOMFIX is not needed in GStreamer-1.20 or later.** Thanks to David
Ventura https://github.com/DavidVentura/UxPlay for the fix and also for
getting a fix into gstreamer-1.20.
