I just optimized the fill routine to only scan adjacent pixel runs 
once.  It now allocates a lot less items in the point queue, and runs a 
bit faster as well.  Let me know if you are still having problems.

Yes I am :(

- open Winwistas.svg (I sent you link yesterday)

- press u

- tolerance = 67

- click in the topmost point of the logo but inside the frame (a
couple pixels lower than the frame)

- freezes, sucking all memory :(

OK, I added another bitmap check.  The already-rendered bitmap is also 
checked to see if the pixel is added.  I wasn't 100% sure I would need 
the check, but it looks like I did.  With the new code, those 
instructions you sent me no longer locks up Inkscape, and the fill 
proceeds as expected on my machine.

Yes, now it's fixed, thanks a lot!

One more thing I'd like to see in this tool: tracing in HSL channels.
That is, have a "Fill by:" label and H, S, L checkboxes in the
controls bar. By default all of them are on and this gives the same
result as now. But I can leave only H on and trace a blue area on a
red background, even if they are very close in S and L. Or have only S
checked and trace a bunch of bright flowers on a dull (low saturation)
background. Or have only L and trace the area of similar level of
lightness ignoring differences in hue or saturation. I think that
would be quite useful in many cases.

Yes, if you output text to STDERR it will be shown to the user in a
dialog box.

While I would say that the default configuration of bugzilla us
unusable, I really like the GNOME bug tracker.

Also, I think we shouldn't switch to something that can't use bug buddy
someday.  I think that utility would get us more stack traces (as it
pretty much does it for the user) with our bugs.

That looks neat.  Is there anything we need to do to make Inkscape a
valid project for you to work on?

NEW: Command line options

Hey,

So I added in some new command line options that are fun.

* --verb-list will list all the Verb IDs and their names in Inkscape.
This makes writing your own menus and hotkeys much easier as you can
easily find out what the choices are.

* --verb followed by a verb ID allows you to specify a verb to be called
on every document opened by Inkscape initially from the command line.

* --select followed by a node ID will allow you to add a node to the
list of selected objects.

Now, initially I thought these would be really good for performance
testing, and that was my driver.  You could do something like this:

$ time inkscape --verb=FileClose my_complex_file.svg

And get a reasonable number.

But, now, with the selection, I think it can be much more useful than
that.  You can call effects, or any other verb, then FileSave and
FileClose to automate all kinds of things on your diagrams.

	Have fun,
		Ted

How can you chain them together on the commandline? That would be great

Well, all I know about the arrangements is what I've read from that
URL. (which was the English version as I pasted it, but now I get only
the Finnish version O.o )

That is, for now there is nothing necessary for you to do, but if I
could name some contact person from Inkscape project, it would be good.
I think this is about the same, as mentor in GSoC, though here it's not
required to have one.
