I confess that I have bad habits with other tools. For example in the
visual studio's datagridview, you have always an empty line in the end
of the list to create a new line.
That this behavior I tried to reproduce here. However in the rev's
datagrid when you are at the end of the list you are at the end ;)
I have no problem with that.
Know if we are in an empty area is interesting anyway for other uses.

Thanks for the quick implementation, Trevor ;)

It is as the scrollbar was transparent (a blendlevel near 100),
however it seems not, I checked ;)

Thanks for the code preview, I will give it a try ;)
