That's not a solution. People advocated for years that images  
shouldn't be used for textual content and that changed exactly  
nothing. The only thing that could make textual images go was always  
going to be support for arbitrary fonts, because it then becomes  
easier to do it and to maintain than if you have to pull up Photoshop.

This is the sort of area that I was thinking about exploring with my  
Canvas SVG stuff[0]. I think that if you add built-in support for hit- 
testing and focus to canvas you open the way to serendipitous  
accessibility (which is what we want). The problem with that is that  
it risks nullifying the initial advantage of canvas which is that it  
is simple and low-cost  I'm unsure as to where the best trade-off lies.
