MicroTeX: set the LaTeX string and replace/substitute so that MicroTeX can render it (but do not actually render).

update_image()

void TeXView::TeXArea::update_image	(	std::shared_ptr< TeXEngine::TeXRequest >	content,
		double	scale
	)

Update the visible image from the pixbuf.

Call this in order to propagate changes to the pixbuf (e.g. from re-running the TeXRequest) to the visible widget itself.
