read

Reads the snip's data from the given stream.

• (send a-wx:text-snip read len f) -> void
      len : small integer
      f : wx:media-stream-in% object

  The len argument specifies the maximum length of the text to be read. (When a text snip is written to a file, the very first field is the length of the text contained in the snip.) This method is usually invoked by the text snip class's read method.
