Why would you say something like this?  Working interactively with an  
SVG canvas is especially useful in a large set of applications.

A wxDC can draw anything, if you're willing to put the effort into  
it.  wxArt2d is especially handy because it continues to treat your  
drawing as objects (at almost any level of hierarchy) even after  
placing it on the DC, so you can hook it to move things around pretty  
easily - basically what you'd do if you had to write it yourself, but  
in this case, someone already did it for you.. :-)  wxSVG appears to  
mostly be intended for rendering SVG into a DC, but not really working  
with it except at the individual element level, which is too fine- 
grained for managing most user interactivity.  If that's all you need,  
it may or may not be better than wxArt2D (someone who knows better,  
feel free to correct me - I'm just going off what documentation I  
could find).
