+
+A wxSVGFileDC is a  device context onto which graphics and text can be drawn, and the output
+produced as a vector file, in the SVG format (see http://www.w3.org/TR/2001/REC-SVG-20010904/ ).
+This format can be read by a range of programs, including a Netscape plugin (Adobe), full details at 
+http://www.w3.org/Graphics/SVG/SVG-Implementations.htm8 
+
+Vector formats may often be smaller than raster formats.
+
+The intention behind wxSVGFileDC is that it can be used to produce a file corresponding 
+to the screen display context, wxDC, by passing the wxSVGFileDC as a parameter instead of a wxDC. Thus,
+the wxSVGFileDC is a write-only class.
+
+As the wxSVGFileDC is a vector format, raster operations like GetPixel are unlikely to be supported.
+However, the SVG specification allows for PNG format raster files to be embedded in the SVG, and so 
+bitmaps, icons and blit operations into the wxSVGFileDC are supported.
+
+A more substantial SVG library (for reading and writing) is available at 
+http://www.xs4all.nl/~kholwerd/wxstuff/canvas/htmldocbook/aap.html

+Please notify Chris Elliott (biol75@york.ac.uk) of any bugs. Look in wxWindows\contrib\docs\latex\svg for the 
+documentation
