largepixmap: Fix the selfcopy issue.

If the source and destination are the same pixmap/fbo, and we
need to split the copy to small pieces. Then we do need to
consider the sequence of the small pieces when the copy area
has overlaps. This commit take the reverse/upsidedown into
the clipping function, thus it can generate correct sequence
and avoid corruption self copying.
