The viewer is a viewing and rasterization scroll view component that handles a number of viewing operations including rendering, caching, high level zoom rendering and layout modes.
Viewing represents reading a document and displaying it as the author intended. Through the process of rasterization, it can take document data and convert it into pixels that come together to be rendered on a display.
