| 7 | * Description: This is the header file for the video display module of SAGE. |
|---|
| 8 | * |
|---|
| 9 | * Notes : Since the display window may receive its many pieces from many servers, we need to pass multiple buffers |
|---|
| 10 | * to this class. Each of the buffers passed contains a frame which forms a part (or whole) of the image on |
|---|
| 11 | * the display side. |
