| 8 This class behaves identical to PyChan's Font class except in | |
| 9 initialization. Ratherthan take a name and a get object, this class | |
| 10 takes a fontdef and settings object as explained below. This class is | |
| 11 necessary because the original Font class was too restrictive on how it | |
| 12 accepted objects | |
