Export "set bitmap dimension" and "reset the rendering context to its default state"

[tabatkins]

"set bitmap dimension" and "reset the rendering context to its default state" are used by Houdini Paint API, but they're currently unexported. Export plz?

How can these be usable as-is? The former refers directly to the canvas element. They also seem to accept far too few parameters to be generally usable.

Dunno, I encountered these while trying to prep Houdini Paint API for publication. @bfgeek ?

Hmm... its been a while (these algorithms may have changed since we first referenced them), but looking at those two references in the css-paint-api spec, we could rework it to remove them. E.g. instead of using the "set bitmap dimension" alg in the html spec use our own. "reset the rendering context to its default state" is just used within a note, and can be removed.
