  26  * Verify that GLX_DONT_CARE can be used with bitmask attributes
  27  *
  28  * Page 17 (page 23 of the PDF) of the GLX 1.4 spec says:
  29  *
  30  *    "If GLX_DONT_CARE is specified as an attribute value, then the
  31  *    attribute will not be checked. GLX_DONT_CARE may be specified
  32  *    for all attributes except GLX_LEVEL."
  33  *
  34  * This test verifies that \c GLX_DONT_CARE can be supplied for
  35  * \c GLX_RENDER_TYPE and \c GLX_DRAWABLE_TYPE.
