/*******************************************************************************
* Sitepark.Common.Geometry
*
* object, containing PORTABLE functions for querying window
* and document geometry
*
* getWindowX/Y(): return the position of the window on the screen
* getViewportWidth/Height(): return the size of the browser viewport area
* getDocumentWidth/Height(): return the size of the document.
* getHorizontalScroll(): return the position of the horizontal scrollbar
* getVerticalScroll(): return the position of the vertical scrollbar
*
* Note that there is no portable way to query the overall size of the
* browser window, so there are no getWindowWidth/Height() functions.
*
* IMPORTANT: This object must be defined in the of a document
* instead of the of the document.
