Remarks
This method is widely used in the FastReport. It is called each time when the object needs to draw or print itself.
In order to draw the object correctly, you should multiply the object's bounds by the scale parameter.
cache parameter is used to optimize the drawing speed. It holds all items such as pens, fonts, brushes, string formats that was used before. If the item with requested parameters exists in the cache, it will be returned (instead of create new item and then dispose it).

Fills the control with data.

Remarks
Do not call this method directly. You should override it if you are developing a new component for FastReport.
This method is called when the object needs to save the state. It may happen when:
- saving the report to the file or stream;
- saving the report to the designer's undo buffer;
- assigning the object to another object using the Assign(Base) or AssignAll methods;
- saving the object to the designer's clipboard;
- saving the object to the preview (when run a report).
