+1b. Adding Tango version of the resource.
+-----------------------------------------
+
+While all the bitmaps are provided in XPM format so that they are available in
+all builds of wxWidgets, we also provide most of them in PNG format with full
+transparency support that is not available in XPM. Another advantage of the PNG
+versions is that the icons used are those of the Tango project and so have the
+consistent look, unlike the XPM ones.
+
+So if you an icon exists in http://tango.freedesktop.org/Tango_Icon_Gallery you
+should add it too. For this you need to:
+
+1. Convert the PNG to a C array of bytes suitable for inclusion in the code.
+   This is done using misc/scripts/png2c.py script, e.g. if the variable "f"
+   contains the name of the icon you want to add and you have installed Tango
+   icons in a standard location under a Linux system:
+
+    ./misc/scripts/png2c.py -s /usr/share/icons/Tango/{16x16,24x24}/*/$f.png >
+        art/tango/${f//-/_}.h
+
+   Of course, the same command may be ran with different paths under Windows.
+   Just remember to add both 16 and 24 pixel versions of the bitmap to the
+   header and use the "-s" option to embed the image size in its array name.
+
+2. Add #include for the newly created file to src/common/arttango.cpp.
+
+3. Add an entry to s_allBitmaps array in the same file.
