Thanks! Seems like it also does not support the bias property though...

Sure, I've attached an image. Note that Inkscape has some issues with
the edges, but that's a different problem.
I've also included an image showing how Batik renders the file if I
remove the bias attributes, hence my guess that Opera does not support
the bias attribute.

No, imagine that the image already has alpha=0.5, then adding a bias of
0.5 suddenly does not correspond to a transparent gray zero response,
but rather a transparent white zero response.

Unfortunately I don't have any of those installed, so if someone could
help me test that would be great. I have attached a file that tests
numerous cases using bias (and transparency), if someone could try it on
his/her favourite renderer that would be great.

Tool pointer pixmaps
by Guillermo Espertino
I've uploaded some improved (imho) pixmaps for the tool pointers in this
bug report: https://bugs.launchpad.net/inkscape/+bug/325145
---
The changes are:
- Tweaked the appearance of 3dbox and eraser
- added crosshairs to connector and bucket fill
- new icon for bucket fill
- Unified the appearance of pen and pencil tools
- Unified the size and position of the color dropper icon
The icons had different sizes and positions relative to the crosshairs,
so I tried to unify that.
Now the modified icons fit in a 26x26 square at the upper left of the
total area (32x32) so there is space in the bottom left for potential
modified versions (for instance adding a + sign for addition, like the
gradient tool has).
Some icons (bucket fill, color dropper and connector) have a slightly
different hotspots now, so they'll have to be adjusted.
There are others that can be adjusted, but with these changes at least
the set is more homogenous in size and style.
The pen icon for the bezier tool is in my opinion confusing, since the
pen icon in the UI is assigned to the calligraphic tool. Nobody seems to
matter, though.
----
The only change needed is to check and correct the tool hostpot in some
of them, but I guess that would be a trivial change (that I don't know
how to perform :-)
What do you think?

Tango Icons Ready
by Krzysztof Kosiński
I have completed converting the Tango icon set made by Jesusda to discrete
icons. The only missing icons are in the geometry tool (which doesn't seem
to work anyway), but I'll add them shortly. Should I make it the default for
Linux?
This would be accomplished by installing the contents of a subdirectory
named "tango" to $PREFIX/share/inkscape/icons/hicolor. Windows users would
still see the "hicolor" directory, but could rename the tango directory to
hicolor and see the Tango icons. Linux users could use the old icons by
putting them in ~/.icons/OldInkscape and modifying the index.theme file to
inherit from their theme of choice (Human, gnome, etc.). I'm preparing a
README with detailed instructions.
Regards, Krzysztof Kosiński

Incorrect handling of <text> without <tspan>
by Jimmy
I have been working on a patch for bug:
https://bugs.launchpad.net/inkscape/+bug/167904
sp_te_insert_line
I basically created a working patch (excluding end of string line breaks
and probably spacing issues). The patch checks if the text in contained
in a text box is a child of <svg:text> instead of <svg:tspan> . If this
is true a <tspan> is inserted as a child of the <text> and the string is
transfered to become a child of the <tspan> . this This works but it
fails for strange reasons. If the text box is selected and the cursor is
moved over with the keyboard and a line break is inserted, inkscape
crashes. I traced this back to a problem occurring with the
Glib::ustring::iterator s being used. In the instances that the patch
fails the iterator's values don't match up to their expected value. The
problem also occurs after a line break, an undo, and a repeat of the
line break.
I'm fairly new to the code base so I may be doing things out of order or
failing to call a necessary function.
I'm not exactly sure why this is occurring after these actions are
performed. What can I do to solve this issue. I have posted the code in
question to the bug report. I have a feeling this problem is occurring
from the layout obtained from the SPItem and the actions that occur
afterwards. Thanks

message overwrites rotation value
by Jeremy C. Reed
I had a box that appear to be skewed. So I tried to grab and I saw numbers
flashing on bottom window bar, but it kept getting overwritten with
"Rectangle in layer Layer 1. Click selection to toggle scale/rotation
handles."
Maybe that message should go somewhere else? Or the rotation percentage
should be displayed somewhere else?
What is my workaround for now? Where can I see the number or where can I
manually type it in?
I am on inkscape-21256 (from yesterday's snapshot).
