* The contents of this pref are appended to the flattened string of
* parameters stuffed into GonkCameraParameters by the camera library.
* It consists of semicolon-delimited key=value pairs, e.g.
*
* focus-mode=auto;flash-mode=auto;preview-size=1024x768
*
* The unflattening process breaks this string up on semicolon boundaries
* and sets an entry in a hashtable of strings with the token before
* the equals sign as the key, and the token after as the value. Because
* the string is parsed in order, key=value pairs occuring later in the
* string will replace value pairs appearing earlier, making it easy to
* inject fake, testable values into the parameters table.
*
* One constraint of this approach is that neither the key nor the value
* may contain equals signs or semicolons. We don't enforce that here
* so that we can also test correct handling of improperly-formatted values.
