Concrete picture classes draw in different ways and allow cropping and scaling. Pictures are the basis for doors.
picture character
Represents a picture.
picture header
Identifies a picture type. A picture occupies a single character position. The picture header is stored in the same stream as the text. The picture is stored in a different stream to support deferred loading. When inserting a picture into rich text, the picture header rather than the picture itself is inserted into the text.
picture header factory
Produces picture headers of a single type. Required because pictures are type-extensible.

polymorphic DLL
A DLL that provides some plug-in functionality to another program by implementing a pre-defined interface. They are dynamically loaded by the DLL user during run-time. In Symbian OS, the typical use of a polymorphic DLL is to implement a framework extension. Polymorphic DLLs are sometimes known as provider DLLs.

priority function
ETel priority functions are executed using pre-allocated memory, and hence cannot fail with an out of memory error. Any client can use a priority function, not just the priority client.
