	10	@class wxSVGFileDC
	11
	12	A wxSVGFileDC is a device context onto which graphics and text can be
	13	drawn, and the output produced as a vector file, in SVG format.
	14
	15	This format can be read by a range of programs, including a Netscape plugin
	16	(Adobe) and the open source Inkscape program (http://inkscape.org/). Full
	17	details are given in the W3C SVG recommendation (http://www.w3.org/TR/SVG/).
	18
	19	The intention behind wxSVGFileDC is that it can be used to produce a file
	20	corresponding to the screen display context, wxSVGFileDC, by passing the
	21	wxSVGFileDC as a parameter instead of a wxDC. Thus the wxSVGFileDC
	22	is a write-only class.
	23
	24	As the wxSVGFileDC is a vector format, raster operations like GetPixel()
	25	are unlikely to be supported. However, the SVG specification allows for PNG
	26	format raster files to be embedded in the SVG, and so bitmaps, icons and
	27	blit operations in wxSVGFileDC are supported.
	28
	29	A more substantial SVG library (for reading and writing) is available at
	30	the wxArt2D website <http://wxart2d.sourceforge.net/>.
