Normally this doesn't have to be called as the engine will call this function automatically as soon as the object is rendered. However, to avoid the (sometimes long) setup time for an object while walking around an application can choose to call this function manually in order to increase load time but decrease the time need to setup things later.

Note that the new material MUST have the same size as the old material! If 'newmat' == 0 then the default from the factory will be used again. Note that 'oldmat' will always be compared from the factory and not from the current material the polygon has!

Control how this thing will be moved.
<p>
There are currently two options.<ul>
<li>CS_THING_MOVE_NEVER: this option is set for a thing that cannot move at all. In this case the movable will be ignored and only hard transforms can be used to move a thing with this flag. This setting is both efficient for memory (object space coordinates are equal to world space coordinates so only one array is kept) and render speed (only the camera transform is needed). This option is very useful for static geometry like walls. This option is default.</li><li>CS_THING_MOVE_OCCASIONAL: this option is set for a thing that is movable but doesn't move all the time usually. Setting this option means that the world space vertices will be cached (taking up more memory that way) but the coordinates will be recalculated only at rendertime (and cached at that time). This option has the same speed efficiency as MOVE_NEVER when the object doesn't move but more memory is used as all the vertices are duplicated. Use this option for geometry that is not too big (in number of vertices) and only moves occasionally like doors of elevators.</li></ul>
<p>
Note: it is no longer needed to manually set this option. By default things will use CS_THING_MOVE_NEVER and they will automatically switch to the slightly less efficient CS_THING_MOVE_OCCASIONAL if needed.
