Rodolfo García Peñas (kix)andCarlos R. Mafra af41673dbf Removed scaleDownIfNeeded function (dup code)
The function scaleDownIfNeeded's code is duplicated with the code of
wIconValidateIconSize(), then this function can be removed. The icon
size in the switchpanel should be ~48 pixels, to allow the frame around
the icon. Then, we always should resize the icon to this size. The standard
icon size is specified in WPreferences.icon_size (usually 64 pixels).
