GfxBase->NormalDisplayRows and GfxBase->NormalDisplayColumns are the
height and width of the normal "morerowed" area of a hires
non-interlaced screen.  Equivalently Preferences->RowSizeChange and
ColumnSizeChange are the difference of these values from their nominal
values.

Preferences->ViewXOffset and ViewYOffset are the amounts the view has
shifted (usually up and to the left, I gather they'd be negative in
that case).  These numbers probably represent lores non-interlaced
pixels.
