Detailed Description
A very basic text displayer window. Pass in a chunk of text and this window will display it. You can have multiple lines by putting '\n' characters in the text.
If there is too much text to fit in the window, you can optionally allow the user to drag the text around. Simply define MB_MOVE, and right clicking will shift around the text. Shift and/or Control right drag speeds up the shifting.
Left click to copy to clipboard if MB_COPY is set.
- Todo:
*** need to implement wrapping style
*** SetText(char *s1,char *s2, ...)
// Note to developer: these must not clobber the xymesbar defines:
enum MessageBarTypes;

| ) |
Pass in the new text after the regular window parameters.
Multi-line text is simply a char[] with '\n' characters in it. The text is then copied and stored by line in thetext.
If win_w or win_h are 0, and newtext is supplied here, then win_w and win_h are set to the extent of the message plus pads.

Default is to read in text, and whatever anXWindow reads.
Reimplemented from Laxkit::anXWindow.
References Laxkit::PtrStack< T >::e, Laxkit::PtrStack< T >::n, and SetText().

Append to att if att!=NULL, else return a new Attribute whose name is whattype().
Default is to add attributes for "text", and whatever anXWindow adds.
Reimplemented from Laxkit::anXWindow.
References GetText(), and LaxFiles::Attribute::push().
If allowed with MB_MOVE, this shifts around text that is smaller than the window only within the window boundaries, and shifts around larger text only just enough so that you can see it.
Reimplemented from Laxkit::anXWindow.
