autoHeigh does not work property if grid has horizontal scroll bar

[romankuzmik]

simple add 'style="width:200px;"' to the table tag in 'autoHeight=5 (7 elements)' example from dojox\grid\tests\test_data_grid_autoheight.html. And most likely you'll see only 4 rows instead of 5.

The problem is the view area size calculation algorithm does not include scrolled bar height. And if this bar is displayed then viewable area is the scroller bar height smaller than it have to be.

This is a chicken and egg problem: the grid needs to know if the contents will be scrolled, but it won't know that until after rendering. Marking as "wontfix" because the grid already does enough calculating without adding more to get rid of an edge case.
