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.
