Gets or sets the most bytes of display lists a document keeps, so that rendering a page again (another zoom, another tile) reuses its list while the document is unchanged; the least recently used are dropped beyond it. A list is charged its tables and the images it holds. Zero keeps none: CreateDisplayList() builds a new list on every call. Default 32 MiB.
