No.  It *may* store a pixmap of the entire window.  It also may choose
to compress it; for an xterm window, sufficiently smart compression
schemes need store only a handful of bits per character cell (typically
about 9 or 10 bits - there's more than just the character code to
store).  (Not that I necessarily expect X servers to include
compression schemes that smart.  But if we're being pedantic....)
