Added the ability to ask a ambient layer to keep its ratio when the resolution isn't the default.

You'll have to add this in map properties, for instance if you're want to keep ratio on overlay 0:
<map version="1.0" orientation="orthogonal" width="128" height="128" tilewidth="32" tileheight="32">
 <properties>
  ...
  <property name="overlay0keepratio" value="true"/>
  ...
 </properties>
</map>
