<DD>Renders features based on the map layers and their styles as specified
 in the map context using <code>setContext</code>.

 This version of the method assumes that the size of the output area
 and the transformation from coordinates to pixels are known.
 The latter determines the map scale. The viewport (the visible
 part of the map) will be calculated internally.
