There's no need to save the graphics as individual glyphs. Browsers treat SVG <text> elements like vector graphics, because that's all an SVG is - Scalable Vector Graphic.

So you can warp the text in Corel or Illustrator, then export the entire word or phrase as a single SVG file.

Now just open the SVG in a text editor like Notepad, and it will give you the <path> information for the entire graphic. Just copy/paste this "d" info into your HTML and the browser will now display the text "warped" -- it's just displaying GRAPHICS based on a set of instructions.
