Boris, could you elaborate on this?

As Mike mentioned, Chrome provides first paint time, and I believe IE does
as well.. Looking at the Chrome source, it looks to be the "literal" first
paint:
http://code.google.com/searchframe#OAMlx_jo-ck/src/content/public/renderer/document_state.h&exact_package=chromium&type=cs&l=105

Is that a reasonable definition. If not, why not?
