composite: Fix repaint of borders (v2) 

When going from border width zero to a non-zero border width, the
Composite extension is informed via the ConfigNotify callback. The
call-chain looks like this: compConfigNotify -> compReallocPixmap ->
compSetPixmap -> TraverseTree -> compSetPixmapVisitWindow. However, at
this time, pWindow->borderWidth was not yet updated. Thus, HasBorder()
is false and the window border will not be repainted.

To fix this, thread the new bw through to the window visitor, and
inspect that rather than HasBorder(). For the other callers of
compSetPixmap the border does not change size, so we can pass
pWin->borderWidth instead.
