Hi,

        After reading a tantalizing entry in the SVN log file, I just had to
give the latest version a try at loading SVG drawings that use filters.

Fixed a crash in modifying filter parameters in XML editor.
Fixed filters not appearing, when a file with filters is loaded.

------------------------------------------------------------------------

        The Gaussian Blur example from my book loaded quite nicely:

There are some display issues when the zoom level is greater than 100%
(horizontal discontinuities appear) but overall a very nice development.
I tried varying the blur radius with the XML editor but the drawing was
not updated.

        The Drop Shadow example loaded but did not display correctly.

I got a number of error messages:

(inkscape:718): GLib-GObject-WARNING **: invalid cast from `SPFeOffset'
to `SPGaussianBlur'

(inkscape:718): GLib-GObject-WARNING **: invalid cast from `SPFeOffset'
to `SPGaussianBlur'

(inkscape:718): GLib-GObject-WARNING **: invalid cast from `SPFeMerge'
to `SPGaussianBlur'

        This begs the question, what is the status of filter support?

        A couple of other notes. When reloading the Gaussian Blur file with a
modified blur radius, Inkscape crashed with the error message:

** ERROR **: file sp-object.cpp: line 861 (void
SPObject::releaseReferences()): assertion failed: (this->hrefcount == 0)
aborting...

Trying to drag the right resize handle of the text box doesn't work;
dragging the left handle does.

        It's great to see the progress made with SVG filter support!
