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?
