Summary:
Get rid of eps files,
change all doxygen '\image latex' references to eps files to png/jpeg instead,
convert doxygen images from gif -> png (to support html+latex).
Actual operations:
1) svn remove *.eps
2) convert all gifs -> png
3) svn remove *.gif
4) svn add *.png
5) For jpeg/png images, change all \image latex foo.eps .. -> \image latex foo.[jpg,png] ..
6) For gif images, change all \image html foo.gif .. -> \image html foo.png
and (harder to do): change \image latex foo.eps .. -> \image latex foo.png ..
7) Remove EPSFILES macro from documentation/Makefile
and remove eps related dependencies that were added recently

/**
|
|
\class Fl_Choice
|
|
\brief A button that is used to pop up a menu.
|
|
|
|
This is a button that, when pushed, pops up a menu (or hierarchy of menus)
|
|
defined by an array of Fl_Menu_Item objects.
|
|
Motif calls this an OptionButton.
|
|
|
|
The only difference between this and a Fl_Menu_Button is that the name of
|
|
the most recent chosen menu item is displayed inside the box, while the
|
|
label is displayed outside the box. However, since the use of this is most
|
|
often to control a single variable rather than do individual callbacks,
|
|
some of the Fl_Menu_Button methods are redescribed here in those terms.
|
|
|
|
When the user picks an item off the menu the value() is set to that item
|
|
and then the item's callback is done with the menu_button as the
|
|
\c Fl_Widget* argument. If the item does not have a callback the
|
|
menu_button's callback is done instead.
|
|
|
|
All three mouse buttons pop up the menu. The Forms behavior of the first
|
|
two buttons to increment/decrement the choice is not implemented. This
|
|
could be added with a subclass, however.
|
|
|
|
The menu will also pop up in response to shortcuts indicated by putting
|
|
a '\&' character in the label(). See Fl_Button::shortcut(int s) for a
|
|
description of this.
|
|
|
|
Typing the shortcut() of any of the items will do exactly the same as when
|
|
you pick the item with the mouse. The '\&' character in item names are
|
|
only looked at when the menu is popped up, however.

\todo Refactor the doxygen comments for Fl_Choice changed() documentation.
|
|
|
|
\li <tt>int Fl_Widget::changed() const</tt>
|
|
This value is true the user picks a different value. <em>It is turned
|
|
off by value() and just before doing a callback (the callback can turn
|
|
it back on if desired).</em>
|
|
\li <tt>void Fl_Widget::set_changed()</tt>
|
|
This method sets the changed() flag.
|
|
\li <tt>void Fl_Widget::clear_changed()</tt>
|
|
This method clears the changed() flag.
|
|
\li <tt>Fl_Boxtype Fl_Choice::down_box() const</tt>
|
|
Gets the current down box, which is used when the menu is popped up.
|
|
The default down box type is \c FL_DOWN_BOX.
|
|
\li <tt>void Fl_Choice::down_box(Fl_Boxtype b)</tt>
|
|
Sets the current down box type to \p b.
