           Summary: Horizontal scrolling on DataGridView doesn't match
                    .NET (not smooth)

Test case

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.9.1b4pre) Gecko/20090317 Shiretoko/3.1b4pre (.NET CLR 3.5.30729)

See test case.
We have a simple DataGridView with 5 columns.

With .NET, when scrolling vertically, you move row by row. Horizontally,
however, scrolling is smooth, pixel by pixel. (On a side note, on my computer
with the attached test case, .NET has repaint problems when scrolling
horizontally: cell text gets messed up, then scrolling vertically fixes it)

With Mono, vertical scrolling matches .NET, but horizontal scrolling happens
column by column, not pixel by pixel. This also causes accessibility problems.
For example, try accessing the right-most column of the test case just by
scrolling: it'll be cut, you'll only be able to see a part of it.

Reproducible: Always
