Notes on HTML Reflow - Archive of obsolete content
these are dispatched directly from the presentation shell (e.g., nsipresshell::stylechangereflow), and affect the entire frame tree.
...to request (or schedule ) an incremental reflow (e.g., in response to a change in the content model), a reflow command object is created and passed to the presentation shell via the nsipresshell::appendreflowcommand method.
