This is used as a finalization handle for forms - in previous systems,
|
|
|
41 |
a shallowCopy of a form was responsible to destroy the underlying
|
|
|
42 |
devices bitmap. To make the memory requirements smaller and to speed up
|
|
|
43 |
bitmap creation a bit, this lightweight class is used now, which only
|
|
|
44 |
keeps the device handle for finalization.
