Changes:
World Wind General & Plugin Mgr

    * Added code to improve Drag&Drop handling for plugins
    * Fixed ImageOverlay plugin to work with new code changes
    * Added ImageOverlay 4 plugin
    * Added On-Screen clock plugin
    * "Internal" plugins are not ALWAYS loaded anymore. They will load based on a list in MainApplication.LoadSettings() the first time the program starts, then will act like "normal" plugins.
    * Refresh="n" where n is in seconds inside a LayerSet attribute will now affect Icon positions
    * Switch to XPath based XML loading
    * Fix for view frustum bounding sphere intersection (from forum "Larry")
    * Icon memory leak fixed
    * Fix for blank terrain spots (might not work for REALLY close terrain, needs further testing)
    * Implemented a real-time FPS line graph meter
    * Added a "Goto Extent" context menu item when right mouse clicking on a layer in LM. Will move to the geographic center of the extents specified in the Layer file. 


Image Accessor, QuadTiles

    * Cache expiration code is more robust
    * PermDir fix 


Configuration Loader, Overview Form

    * Add CacheExpirationTime support for QTS
    * <CacheExpirationTime> is allowed inside <ImageTileService> or <WMSAccessor> elements
    * <DataExpirationTime> is allowed inside the <ImageAccessor> element
    * Allow for <PermanantDirectory> or <PermanentDirectory>
    * Fix placenames not using <DisplayFont>
    * <Icon> uses <OnClickZoomAltitude>, <OnClickZoomHeading>, and <OnClickZoomTilt>
    * Could not use worldwind:// uri due to XML parsing errors
    * <LayerSet> and <ChildLayerSet> support "RenderPriority" attribute with the following strings: "Icons", "Placenames", "LinePaths", "AtmosphericImages"
    * Fixes problem with ChildLayerSet loading
    * <Icon> now adds another <OnClickZoom> element that allows user to click an icon and have the camera zoom to a specified altitude (in meters)
    * Null terrain accessor from xml should work now
    * Handles new icon OnClick zooming
    * Overview form Home/End zoom works
    * ImageLayer accepts Url images through XML again
    * Higher resolution terrain subsets work again
    * Fixed ChildLayerSet "ShowOnlyOneLayer" attribute error
    * Remove diag log writing for wmsaccessor
    * WMSAccessor works again
    * Allow "CacheDirectory" element in ImageAccessor element for qts
    * Transparent color works for qts again
    * Redirect xml files are cached for offline access
    * Booleans from xml are parsed "smartly"
    * Struts back (again)
    * Redirect allowed from ChildLayerSet -> remote LayerSet file
    * Allows to split a category like "Images" into multiple xml files and still have them group in the Layer Manager
    * Url based layer xml files (check @Images.xml)
    * Switching back and forth between worlds works again
    * Overview form can launch icons from mouse click
    * New setting in World.Settings for allowing constant rendering even when 3d form is unfocused
    * Revert changes to "strut removal"
    * Change Texture format conversion to DDS using a Software-based reference device
    * Should help move this operation from the GPU to the CPU to minimize frame rate studdering
    * Fixed strange 180/-180 boundary line problem
    * Involved a different algorithm for the Quaternion4d.Slerp method
    * Mouse is now more responsive at super-high zoom levels
    * Camera is now more precise
    * Single to double precision calculations (should stop the "jitters")
    * Changes to QuadTileSubset to make the mesh work with higher precision
    * Range transparency for jpegs <TransparentMinValue>0</TransparentMinValue> <TransparentMaxValue>30</TransparentMaxValue> (in place of <TransparentColor>) 


Shapefiles

    * Filtering for shapefile points
    * Shape points optimized for faster rendering
    * Shapefiles PointType renders "points" now (finally)
    * Random color assigment of lines in shapefiles works again
