The following clearly says "Inkscape Fund":

The above does not seem to be (directly) related to linuxfund.org.

Oh, thanks for pointing out. That's the first time I hear about it. I
cannot help you there other than saying that the page was last updated
in August 2008 in SVN, so it looks like Ted or Bryce might have the
answer for you.

It would be best if the slider had a limited range, but you could
input an arbitrary value (or a value from a much larger range) using
the spinbox.

The easiest fix is to set the sliders to Gtk::UPDATE_DISCONTINUOUS
update policy, but this will prevent the display from updating during
the drag. Apparently there is no way in GTK right now to get the
correct behavior!

It was created to collect donations and also for Mentors from GSoC who
would rather the payments go to the project to have a place to defer
them to. It's primarily used to assist with developer's travel needs to
get to conferences and such.

I didn't think about it. It looks like a promising idea. Windows has
ZwCreateProcess, which is an undocumented NT function that works like
fork() including copy-on-write shared memory between the parent and
child processes, so in principle this is possible. It would be wise to
push the Win32 fork() implementation to Glib before using this.

We could have one "master" instance that does all the initialization,
handles preferences file writes, registers itself on DBus, and forks
the "slave" window processes. The code executed in master after
initialization should be reduced to minimum, so that a bug is
unlikely.

We should do the following: if the option parsing bit decides that we
are being run in non-GUI mode, we should not contact any other
processes. If it decides we are being run in GUI mode, we should
submit the results of option parsing to the master process, which will
take care of performing all the work described in the command line.

Forking a process from master when in command-line mode could
sometimes be desirable, as it would speed up the execution of many
Inkscape commands in quick succession.

I also have to admit that it gets really complicated with forks, the
master process, etc. so going for the simpler but less stable
single-instance solution might be better for now. Once there is a
fork() implementation in Glib, and the D-Bus binding and GSettings get
merged into GIO (which should happen soon), we could start working
towards a multi-process architecture.

Regards, Krzysztof

Oh well, I've just added the link to menu in includes/navigation.php
and populated the translatable message over

includes/localized-cs.inc
includes/localized-de.inc
includes/localized-en.inc
includes/localized-es.inc
includes/localized-fr.inc
includes/localized-it.inc
includes/localized-ja.inc
includes/localized-ru.inc
includes/localized.inc

With luck the fund will be more evident now.

Truly yours,

The other problem, as many times pointed out before, is that we do not
tell users what some particular options mean (e.g. most of Turbulence
or "Kernel Unit Length") and what units are used. Some tooltips are
absolutely unhelpful, e.g. the one for Constant says "This constant
affects Phong lighting model".

This could be solved in part if we had a GIMP-style context sensitive
on-line reference. But that's another story.

There are a few ways to get good behavior. Some of these have come up for the color sliders. For this area the two big things to look at are using the might-be-more calls for undo and also to "debounce" the input from the slider so as to not trigger as many changes as the user moves things quickly.

While the former will probably give some of the best 'fix' for this bug, the latter has potential to significantly improve the user experience. When I applied this to the color sliders it technically became slower, but to the users it felt much faster. It trades of raw numeric crunching speed for improved responsiveness to the user.

But again, the root cause of the bug report appears to be from not using our proper under system calls. This may be direct or indirect. If it is the latter (function triggers events that calls functions that in turn register undo changes, etc.) then it might take a bit of cleanup to fix without breaking other cases.
