Good to know.

There is this decription of what the individual libraries do:
http://lists.freedesktop.org/archives/mesa-dev/2015-September/095856.html
hmm, where is that libGLX?

can you draw a graph of the dependencies between the libraries? Or does
something like this exist already?

isn't the purpose to have one for all vendors?

Good, we cn start putting that under pkg-nvidia for now, but in the end
this should probably live under the hands of the X/MESA maintainers.
We should talk to them about this, you mentioned that earlier ... if you
want, you can start that discussion (making sure that pkg-nvidia-devel
stays Cc:ed).

I don't want that  :-)

Nice, but maybe wait with committing until I have 352 in sid and
everything merged through to 358. (Only waiting for 349.16-2 to pass the
buildds.)

NACK. For the beginning I want to ship nvidia's version of these
libraries, this seems to be too much work in progress. There aren't any
tags, yet, so do we know what commit should correspond to the shipped
binaries ...
And I want ship them directly in /usr/lib without any redirecting
alternatives. :-)
Once someone else starts to adopt them we should switch to the
separately packaged versions.

Trying to understand the "new" libEGL works ...
* nothing seems to use libOpenGL right now
* libEGL.so.1 is a stub and depends on libGLdispatch
* libGLdispatch is used by libEGL, libOpenGL
* the we have libEGL_nvidia.so.0 and libnvidia-eglcore.so.355.11
* libnvidia-eglcore.so.355.11 is used by libEGL_nvidia.so.0 and
  libGLES*.so.355.11
* libEGL.so.1 contains the strings "__EGL_VENDOR_LIBRARY_NAME",
  "nvidia", "libEGL_%s.so.0"
* libEGL.so.1 uses symbol __egl_Main from libEGL_nvidia.so.0
* there is also a string "libGLdispatch ABI version is incompatible with
libEGL.", so libGLdispatch and the libEGL stub somehow need to be in sync

=> we need a separate libegl-nvidia0 package, and that actually needs to
use alternatives
that package may get legacy variants, maybe called
libegl-nvidia0-legacy-ABCxx

libegl1-nvidia will probably go away in the future (if someone else
(MESA) provides a stub libEGL.so.1)
