\r
320 * pixel shift for smooth tile scrolling.
\r
321 * 2. Provide ways to draw a visible part of map. For simplicity with smooth scrolling,
\r
322 * additional row/column is always drawn at the each side of the map. This implies that 'fence'
\r
323 * should have a sprite too. Map is drawn left-to-right, top-to-bottom.
