/* Things to be aware of:
*
* This filepicker, like the mozilla one, does not make an attempt
* to verify the validity of the initial directory you pass it.
* It does check that the user doesn't give it a garbage path
* during use, but it is the caller's responsibility to give a
* sensible initial path.
*
* At the current moment, we instantiate the filepicker directly
* in our contenthandler where there is path verification code
* and else where through our C wrapper, which also does verification.
* If, at a future date, you need to instantiate filepicker without
* using the C wrapper, please verify the initial path. See
* ContentHandler for a way to do this.
