* @param insertHTML HTML or function that returns what to insert into each frame
* @returns array of all browsing contexts in depth-first order
*
* This function adds a browsing context and process id label to each
* child subframe. It also sets the background color of each frame to
* different colors based on the process id. The browser_basic_outofprocess.js
* test verifies these colors to ensure that the frame/process hierarchy
* has been set up as expected. Colors are used to help people visualize
* the process setup.
*
* The insertHTML argument may be either a fixed string of HTML to insert
* into each subframe, or a function that returns the string to insert. The
* function takes one argument, the browsing context being processed.
