picom-10.2-bp156.1.5

- Update to version 10.2
  Fixes:
  * Window border not being considered when calculating its mask
    gh#yshui/picom#950

- Update to version 10.1
  Fixes:
  * A GL texture leak, related to
    gh#yshui/picom#892
  * A crash when shadow radius is set to 0
    gh#yshui/picom#927
  * An undefined symbol error
    gh#yshui/picom#932

- Update to version 10
  * picom now needs libEGL to build
  Notable changes:
  * experimental-backends is now the default. Everything should
    keep working, except the --glx-fshader-win option. The old
    window shader support has been replaced by --window-shader-fd.
    This new shader support has a different interface, so you have
    to adapt your existing shaders.
    gh#yshui/picom#875
  * legacy-backends option has been added so you can go back to the
    old backends, which will eventually be removed.
  * picom.desktop is installed to /etc/xdg/autostart/.
    picom should autostart now.
    gh#yshui/picom#791
  * Shadows and blur now match the shape of the window.
    This includes windows using the XShape extension, and windows
    with rounded corners.
    gh#yshui/picom#882
  * New option: --transparent-clipping-exclude, for excluding
    windows that doesn't play well with transparent-clipping,
    such as screenshot tool windows.
    gh#yshui/picom#663
    gh#yshui/picom#738
  * New backend: egl. It should behave exactly the same as the glx
    backend. Give it a try!
    gh#yshui/picom#878
  Other changes:
  * --help messages have been refactored, leading to clearer code.
    gh#yshui/picom#877
  * picom tries to detect and act on GPU resets. But because of the
    limitation of the X server, this ended up not being very
    useful.
