Elementary els_scroller: Fixed not moving when position is shown.
The scroller shouldn't move when the position requested is already
shown. There were two problems:
1. It was assumed that the cw/ch == requsted w/h which is not true, for
example with entry, we sometimes request to show the cursor which way
smaller.
2. We want to check the bounds *after* making sure we are not showing
"dead space" i.e places that the child does not populate.
