TODO

-- ALMOST DONE : add print/save functionality.  Currently you can save by right
   clicking on the fig window, but you must have nothing in front of
   the window.  I suppose I need to first draw to a pixbuf.  I would
   also like to control the resolution.  

     UPDATE: high resolution printing.  Resolution can be set from the
     command line, but the GUI needs to be updated to allow resolution
     to be set along with filename

-- DONE : fix text size calculations using pango layouts: 
 
-- DROPPED : add a font selection dialog for the axis text

-- DONE enable vertical rendering for ylabels: 
     
-- DONE with pango : enable anti aliasing for fonts

-- DONE enable fancy text labels (eg, greek letters, math symbols,
   superscripts) ala TeX or unicode

-- DROPPED add a color selection dialog for the background, lines, and text

-- DONE allow interactive control of the plot from the python shell after
   it has been launched using the cookbook thread recipe.  

-- write a user guide

-- DONE allow more intelligent choice of tick labels and locs when panning and
   zooming.

-- figure out why the positioning of dialog boxes based on position
   and size of main window and dialog window doesn't work exactly as
   expected.  For example, the width of the dialog box is being
   reported as being much smaller than it is.  Is window pixels the
   unit being returned by for gtk.Dialogs.get_size?  Also, this isn't
   working cross platform.  According to the docs this is better
   handled using size hints -- but I don't know how to use them, yet.

-- vlines and hlines disappear in some instance due to improper
   clipping

-- One the errorbar demo the hlines do not always appear symmetric
   about the x values.  Is there an tranformation or rounding problem
   occurring somewhere?

-- DONE Clip patches outside view port

-- DONE: subplot now takes a kwarg axisbg with color format string
   just as axes does : Allow background color to be set for subplots

-- DONE Expose bug on win32 for axis text

-- Fix floating point bug on panx/pany where 0 is computed as 5e-17
   
   UPDATE: hack workaround.  If the distance of the tickloc from the
   nearest integer is a small fraction of the view lim, just use the
   integer

-- DONE: 2003-05-12 fixed _grab_next_args in figure.py : fmt process
   bug on this kind of plot command (2nd of 3 has no format string)

   plot(t1, p1, 'o', t2, p2, ogtt.times, ogtt.cpeptide, 's')

   
-- DONE xlabel is lower than it needs to be

-- DONE 2003-05-12 Removed some of the state handling of text labels
   so they always redraw: interactive setting of x/ylabels doesn't
   redraw all labels unless you click a forced redraw

-- CLOSED When you change a property using the OO interface in interactive,
   the figure doesn't know to redraw.  

   Some possibilities:

   1) redraw on all interactive commands.  kind of heavy handled

   2) override setattr on artist to signal a redraw event. kind of
      heavy handled

   3) allow derived classes to signal redraw events when nexessary.
      kind of code intrusive.


-- DONE 2003-05-11 on exit from interactive.py call gtk. mainquit

-- DONE 2003-05-11 pan/zoom on axes_demo flushes insets

-- DONE compile pygtk for threads on win32.
  
-- DONE 2004-02-04 There is a bug in vertical rendering of text that is exposed in the
   text, but not the ylabel, command.  It looks like a pixmap or
   images is not being properly initialized, resulting in pixel noise.

-- DONE Fix the way the color map allocs colors.  Use only one DrawingArea
   instead of creating a new one with each call to ColorDispatcher().

   doesn't render to the desired color
