/**
 * 
 * Ok, the Title becomes the first line in the error dialog
 * 
 * The text immediately follows. Then come the "Details". This is a 
 * toggle button with an icon and text but no border and no background. The icon
 * looks like a tree toggle (arrow right or down).
 * 
 * There is then more optional text. The best way to support this is to look
 * in the client properties of the JXErrorPane for any "sub text". Ideally this
 * sub text would be part of the ErrorInfo. Maybe I should just add it there?
 * 
 * Finally come the buttons. If there is no report action and the error < fatal,
 * the shown ok button should say "close". Otherwise, if there is no report action
 * but the error >= fatal, it should say "Exit Application". If there is a report
 * action but error < fatal, it should say "Don't Send" for ok, "Send Report" for
 * the report button. If there is a report action and the error >= fatal, then
 * one button should say "Exit", and the report button should say
 * "Send Report and Exit".
 * 
 * Whenever either button is clicked (ok button or report button), the "close dialog"
 * procedure should occur.
