0.8.2.0 released

[Roland Bock <box2OO6 eudoxos de>]

Hi all,

driven by problems with the marshaller (reported by Eric) and confusion
about top_left and bottom_right, I changed a few things that should make
life easier in the long run. Here is the excerpt from the ChangeLog:


- Removal of struct GtkDataboxValue
- Introduction of struct GtkDataboxValueRectangle
- Results:
  - Changed selection signal API (instead of two pairs of pixel
    coordinates, now one struct of "real" values is sent with the
    signal). Since most applications are interested in values instead
    of pixels, this should simplify application code. It also should
    eliminate signal marshaller problems.
  - the set/get limits functions use parameters, left, right, top and
    bottom instead of top_left and bottom_right (which led to much
    confusion in the past).
  - similar with the get_extrema_function
  - in order to transform pixel coordinates into values and vice
    versa, there are now four functions:
    gtk_databox_value_to_pixel_x
    gtk_databox_value_to_pixel_y
    gtk_databox_pixel_to_value_x
    gtk_databox_pixel_to_value_y

Have fun,

Roland
