+ Relative Viewport for Graphics Inclusion
+ Boris Veytsman
+ v1.0, 2011/08/27
+
+
+Package graphicx provides a useful keyword viewport which allows to
+show just a part of an image. However, one needs to put there the
+actual coordinates of the viewport window. Sometimes it is useful to
+have relative coordinates as fractions of natural size. For example,
+one may want to print a large image on a spread, putting a half on a
+verso page, and another half on the next recto page. For this one
+would need a viewport occupying exactly one half of the file's
+bounding box, whatever the actual width of the image may be.
+
+This package adds a new keyword rviewport to the graphicx package
+specifiying Relative Viewport for graphics inclusion: a window defined
+by the given fractions of the natural width and height of the image.
