Definitely support for advanced transformations of text using shapes and
resizing and all other fun stuff is expected. It is left to the web
developer to decide how to implement this behaviour. For example, I may
render text onto the canvas at a certain location, but on a event, clear
that area and then resize and then draw the text at the same location.

My knowledge of SVG is a little weak, but if the content is to be
created dynamically through Javascript, I am not sure if SVG will be
able to support. Isn't SVG tied to a file defining the content?

As a web developer, I do not plan on using the <canvas> for static
bitmap drawing, I definitely want to be able to create dynamic content
including text.
