[Xcb] use of xcb_poly_text_8

[Barton C Massey]

That the protocol description cannot accurately capture
xcb_poly_text_8 is an outstanding bug in XCB.  For now, if
you want to use xcb_poly_text_8, you have to assemble your
request manually.

Anyway, I think what you want for what you're trying to do
is xcb_image_text_8.  The semantics of PolyText8 are quite
complicated; see the X Protocol document
  http://www.msu.edu/~huntharo/xwin/docs/xwindows/PROTO.pdf
for details.

Hope this helps.
