/**
 * Places a Marker on the right place.
 * <p>
 * how it works:
 * <ul>
 * <li>first it searches in the files map to find the right resource to
 * a file name.
 * <li>if no such resource can be found, but the project is available,
 * then the marker will be placed on the project.
 * <li>tries to put the marker on the right place. With errors coming
 * from pre-processed files, it can happen that their column number
 * point to full wrong, or not even existing positions.
 *
 * </ul>
 *
 * Please note that the textFileBufferManagers are created only once for
 * every file resource, their disconnection is done in the dispose()
 * method.
 *
 * @see #dispose()
 *
 * @param fileName
 *                the file name
 * @param startLineNumber
 *                the line number of the beginning of the error or

 * @param startOffset
 *                the offset of the beginning of the error in line given
 *                by startLineNumber or <code>-1</code>
 * @param endLineNumber
 *                the line number of of the ending of the error or

 * @param endOffset
 *                the offset of the end of the error in line given by

 * @param type
