Bug 699667: Remember to update gstate pointers when showing patterns.

pdf_show_pattern() may resize the pdf run processors gstate array. In doing
so any pointers to it saved by called will become stale. Similarly to
pdf_begin_group() pdf_show_pattern() now returns the updated pointer to the
top of the gstate stack.

For the same reason pdf_show_pattern() can not be given a pointer to a gstate
stack entry and continue using it after the gstate array has been resized. So,
have pdf_show_pattern() take an index to the desired state instead.
