Log:
Fix #2579: Symbols are rotated with plot to HP printer landscape
https://trac.osgeo.org/mapguide/ticket/2579
This defect happens on Autodesk Map 3D. But it is an issue of Stylize Engine. The detail step is: 
1.Open Autodesk Map 3D 
2.Go into paper space and select a Landscape paper size 
3.Plot to an HP plotter 
Expected result: Drawing will plot the drawing as defined. 
Actual result: The symbols in the legend are rotated 90 degrees 

This issue only happens on point symbol. The reason is that Map 3D uses method tylizationUtil::RenderCompositeSymbolization?() to create the symbol in legend. I checked the implementation and found that this method doesn't account for the viewport rotation. The issue is fixed by add the viewport rotation.
