When this comment was written, it wasn't clear how the library was going to
figure out which back-end driver to load.  Since then, the wrapper has been
updated to make DRI2 that "VDPAU-specific X extension."

(version 2, supercedes "Clarify type of source_surface")

VDPAU takes special action if source_surface is VDP_INVALID_HANDLE,
not if it is NULL, in both VdpOutputSurfaceRenderOutputSurface
and VdpOutputSurfaceRenderBitmapSurface.

Allow the user to specify the location of the backend driver,
via the VDPAU_DRIVER_PATH environment variable. This allows
easier testing of VDPAU backends without the need to rebuild
libvdpau.

Inspired by LIBGL_DRIVERS_PATH from mesa.

VdpPictureInfo should not be a pointer, otherwise the
VdpDecoderRender function signature asks for a pointer to a pointer.
But it really does expect a pointer directly to e.g. VdpPictureInfoH264.

  * Fix Doxygen warning; it gets confused by quotes.
  * Add subsection names, so part of the title doesn't get swallowed as the
    subsection name.
  * Document data required from MPEG-4 Part 2 & DivX bitstream.

* Add a --with-module-dir configure parameter.

* Pass the moduledir into the wrapper.  Use it to construct the path to search
  for drivers.  Require drivers to end in a ".1" version, in case we ever want
  to rev. the interface between the wrapper and the drivers.

* If no driver is found in the new module dir, look for one in the default
  search paths.  This is intended to find libvdpau_nvidia.so for drivers that
  predate the change to move it, and can be removed in the future.

* Stash the moduledir into vdpau.pc.  Drivers can find this with
  `pkg-config --variable=moduledir vdpau`.

* Add a version to libvdpau_trace.so in case the interface between it and
  libvdpau.so ever changes.

* Install libvdpau_trace.so.1 to moduledir instead of libdir.
