+= How to create the pixel icons.
+
+== update-list.png
+
+Was taken from the Oxygen Icon set (where rendering is done by inkscape).
+prerendered in green.
+
+The color was adapted on the pixel version with gimp
+by visial matching shades of blue in the other icons.
+
+Gimp tools used: 
+Menu -> Color -> colorize.. :
+  with parameters approx 210, 65, 15
+Menu -> Color -> Curves:
+  Adding more billiance by dragging the ligher blue color shades more apart.
+  So from the default curve make it go a little bit steeper for 4/5 
+  of the way and then less steep.
+
+== write-into / write-remove
+
+Original files: oxygen-icons_4.13.0.orig.tar.xz
+./svn-commit.svgz -> write-remove
+./svn-update.svgz -> write-into:
+	Using inkscape to move the arrow up.
+
+Rendered with inkscape to 48pixel height.
