The text being parsed, and every formats being read, the last thing to do is to organize the text. This pass is quite simple: it tries to put every !h_Object! in "screen lines". So this pass creates a new table of !h_Scrlines!, stored in the !hTxt! structure too.
Each screen line is defined by a position in the text. To draw more quickly, some graphical information are kept in the structure: !width!, !nb_space!...
Note that a !h_ScrLine! can start in a middle of an !h_Object!. The only example is if the !h_Object! is a !HOBJECT_TEXT!. For very long text without format changing, the !pos_txt! of a !h_ScrLine! can point in the middle of the !h_Object!.
