where best to set fontFamily?

[cindyloo]

I am setting the fontFamily at the onPageRenderSuccess(page) handler on <Page> but it seems to me this should be set and calculated Before the sizing and rendering of the DOM (glyph calculations, etc). I've spent a day looking at it and I've played around trying to set the fontFamily in one of each of the page's handlers (

  onLoadSuccess={onLoadSuccess}
        customTextRenderer={onCustomTextRendererSuccess}
        onGetTextSuccess={onGetTextSuccess}
        onRenderSuccess={onPageRenderSuccess}

to no avail. Where does this need to happen? I don't see much in the way of figuring out how to do this (standard fonts are now within package), so what am I missing? TY

textlayer Is the best, because we can only edit that font, not the underlying canvas one.
