+  This function copies a rectangle of dimension "width" by "height" 
+  from the VASurface indicated by "surface" to the GLXPbuffer
+  identified by its XID "pbuffer_id".  The locations of source and
+  destination rectangles are specified differently for the VASurface
+  source and the GLXPbuffer destination as follows.  On the VASurface,
+  the rectangle location is specified in the usual X-Window fashion
+  with srcx and srcy indicating the location of the upper left hand
+  corner of the rectangle relative to the VASurface origin (the upper
+  left hand corner of the XvMCSurface with positive Y axis going in the
+  down direction). On the GLXPbuffer the rectangle location is
+  specified in the usual OpenGL fashion with the dstx and dsty
+  indicating the location of the lower left hand corner of the
+  rectangle relative to the GLXPbuffer origin (the lower left hand
+  corner of the GLXPbuffer with the positive Y axis going in the
+  up direction).
+
+  The "draw_buffer" takes the same OpenGL enums that glDrawBuffer()
+  takes (ie. GL_FRONT_LEFT, GL_FRONT_RIGHT, GL_BACK_LEFT, GL_BACK_RIGHT,
+  GL_FRONT, GL_BACK, GL_LEFT, GL_RIGHT or GL_FRONT_AND_BACK).  This
+  indicates which buffer of the GLXPbuffer is to be used for the
+  destination of the copy.  Buffers specified in the "draw_buffer"
+  that do not exist in the GLXPbuffer are ignored.
+
+  "flags" may be VA_TOP_FIELD, VA_BOTTOM_FIELD or VA_FRAME_PICTURE.
+  If flags is not VA_FRAME_PICTURE, the srcy and height are in field
+  coordinates, not frame.  That is, the total copyable height is half
+  the height of the VASurface.
