<h3 style="font-weight: bold;">Landscape</h3>
<span style="font-weight: bold;"></span>Six attributes hold the information about a tile.
This can be seen in the <a href="landscape.html">Landscape</a> document. This page tries to give an overview of used and free bits of
the array so you can quickly see what is used and what is not.
<ul>
  <li><span style="font-weight: bold;"><span class="free">O</span></span> - bit is free</li>
  <li><span style="font-weight: bold;"><span class="used">X</span></span> - bit is used</li>
  <li><span style="font-weight: bold;"><span class="abuse">&nbsp;</span></span> - bit of attribute is abused for different purposes</li>
</ul>
<p>
<ul>
  <li><span style="font-weight: bold;">type_height</span> - 8 bits in size, stores tile height (lower 4 bits) and tile class (upper 4 bits)</li>
  <li><span style="font-weight: bold;">m1</span> - 8 bits in size, used to identify the owner of that tile (eg piece of rail, bridge, etc.)</li>
  <li><span style="font-weight: bold;">m2</span> - 16 bits in size, used to identify the index of the given tile (object) in the (object-)array</li>
  <li><span style="font-weight: bold;">m3</span> - 8 bits in size, is used for general storage</li>
  <li><span style="font-weight: bold;">m4</span> - 8 bits in size, is used for general storage</li>
  <li><span style="font-weight: bold;">m5</span> - 8 bits in size, is used for general storage</li>
  <li><span style="font-weight: bold;">m6</span> - 8 bits in size, special meaning : lower 2 bits only valid in tropic climate, upper 2 bits for bridges</li>
</ul>
