canvas: move to separate CGI script

* stream: and passFd is now client-based, and accessible for buffers
* Bitmap's width & height is now int, not uint64
* no more non-network Bitmap special case in the pager for canvas

I just shoehorned it into the static image model, so it still doesn't
render changes after page load. But at least now it doesn't crash the
browser.
