If you scroll a tilelist it just jumps from one row of tiles
to the next. even if you use liveScrolling.
I want the items to look as though they are sliding when you
drag the scroll bars up and down. which is more natural looking
than just jumping to the next line.
I think to achieve this I need to somehow set the tilelist to
be big enough to fit all of the tiles in it without scrolling. then
embed that in a vbox and make the vbox scroll and not the tile
list. I am unsure how to achieve this without ended up with 2
