Component Properties
When a component is selected then a component's properties can be changed by pressing
the property button 
When newly created, a component is already selected. To select another component then
just click on it.
The properties that can be changed depend on the type of component being edited.
Usually these will include:
- The coloring
- The shininess
- The texturing (except for 2D text)
- The font in 2D and 3D text components
