gtktiledviewer: align to top/left for Calc

Otherwise when zooming out enough that not all available space is used,
the default horizontal/vertical centering happens, and the row/column
headers and the tiles become out of sync.

Also revert to the previous default window size, I'm not sure why that
was necessary. Currently checking the mentioned situation (empty Writer
document with comments only) does not require this larger size, and
testing two views is easier with the smaller size.
