/**

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