12description: |-
13  The Dewarp Engine provides high-performance dewarp processing for the
14  correction of the distortion that is introduced in images produced by fisheye
15  and wide angle lenses. It is implemented with a line/tile-cache based
16  architecture. With configurable address mapping look up tables and per tile
17  processing, it successfully generates a corrected output image.
18  The engine can be used to perform scaling, cropping and pixel format
19  conversion.
