16Filename:    ExampleFrameListener.h
17Description: Defines an example frame listener which responds to frame events.
18This frame listener just moves a specified camera around based on
19keyboard and mouse movements.
20Mouse:    Freelook
21W or Up:  Forward
22S or Down:Backward
23A:        Step left
24D:        Step right
25             PgUp:     Move upwards
26             PgDown:   Move downwards
27             F:        Toggle frame rate stats on/off
28                         R:        Render mode
29             T:        Cycle texture filtering
30                       Bilinear, Trilinear, Anisotropic(8)
31             P:        Toggle on/off display of camera position / orientation
