  10     This is AROS specific file used for versioning the Gallium3D interface.
  11     Since the gallium interface (see DEVELOPMENT:include/gallium) on AROS is
  12     exposed from gallium hidds to client modules (at this time mesa.library)
  13     there is a need to make sure that the interface that hidd was compiled with
  14     is the same as the interface the client was compiled with.
  15
  16     IMPORTANT: With each change of the gallium header files, this value needs to
  17     be increased. The client will only use the gallium hidd if the versions
  18     exactly match. This safety is implemented because the Gallium3D interface
  19     is originally treated as internal and does not need to be backward
  20     compatible. In fact, in most of the cases, changes made are not backward
  21     compatile.
  22
  23     If this value is not increased with each headers change, it will lead to
  24     random crashes if client was compiled with different version of interface
  25     than the hidd.
  26
  27     This values is meant to be compiled in into each gallium hidd driver and
  28     each gallium hidd driver client.
