(modified patch from <p.hornby@arrc.csiro.au>)

fix gcc warning

patch 4

add comment

work around the fltk bug so that we don't really require fltk 1.1.5

test fltk version inside #if HAVE_FLTK

patch 3

FLTK >= 1.1.5 is now required to compile Gmsh: the FL_Scroll widget in
FLTK < 1.1.5rc1 is buggy (clear() destroys the scrollbars)

Thanks to Nicolas for the bug report !

trying to fix nicolas' compile problem

only call fc->position() the first time

forgot to add x() and y()

subclass the original file chooser and move it into the GUI class, so
that we can set its position (the FLTK folks don't want to patch the
standard file chooser, so this is the only solution...)

one more

add a couple more screenshots

fix typo

add menu divider after help->current options

fix plugin option memory leak

add "credits" button in about window (and remove obsolete gmsh bitmap)

fix problem with new dynamic menus and plugin dialogs (unfortunately, this
re-adds the (small) memory leak in the GUI)

- removed the sort view list stuff: it's a bad idea since we re-sort
the list in many places when we search/replace through it

- add a simple "set visibility->all on/off" switch

added ability to sort the list of views (by name, by visibility)

better names for the combined views

cosmetic

generalized the "spatial" Combine so that we can also combine by view name

cleaned up View->Combine by defining a new option (to determine if
we should remove the original views after a "Combine" or not)

In "Combine TimeSteps", if the original views don't have meaningful
time data, create a time index

nicer: use kill() instead of a system() call
