drscheme:debug:show-error-and-highlight in DrScheme Tools Functions

• (drscheme:debug:show-error-and-highlight msg exn highlight-errors) -> any
     msg : string?
     exn : (or/c any/c exn?)
     highlight-errors : ((listof srcloc?) (or/c false/c (listof (list/c (is-a?/c text%) number? number?))) . -> . any)

  The first two arguments are the same as the arguments to the error-display-handler. This function prints the error message to the current-error-port, like the default error-display-handler and also calls highlight-errors to do error highlighting. It is be passed the stack trace for the error message.

  This function should be called on the same thread/eventspace where the error happened.
