+pixmap paths
+============
+there is no lookup order, but exactly one place to search for pixmaps.
+You can either:
+ - specify a full pathname (PLEASE, don't!), with a leading slash.
+ - specify a relative pathname, without leading slash.
+ The file will be searched for under the default skin image directory.
+ use this to refer to pixmaps which are included in the default
+ distribution, i.e. no skin specific stuff but for example the
+ number bitmaps etc.
+ - relative to the skin's directory (with a leading "~/").
+ ~ in this case can be seen as the skin's "home directory", that's the
+ place where the skin.xml is.
+ use this if you are building a skin.
