lyx_mirror/src/ParagraphMetrics.h
Abdelrazak Younes b2126408cf This commit do the Model/View separation of the LyXText and Paragraph classes. The separation is mostly complete for the Paragraph class but some more transfer should occur for the LyXText class.
* ParagraphMetrics.[Ch]: new files

* TextMetrics.[Ch]: new files.

* lyxtext.h/text2.C/text3.C: some code transferred to the TextMetrics class.

* paragraph.[Ch]: all screen oriented code transfered to ParagraphMetrics class.

* BufferView:
 - text_metrics_: new TextMetrics cache private member.
 - textMetrics(): new access method.
 - parMetrics(): ditto.
