'Locates a bitmap file of the name name.xpm or name in one of the
bitmap directories (see the tix_addbitmapdir command above).  By
using tix_getbitmap, you can avoid hard coding the pathnames of the
bitmap files in your application. When successful, it returns the
complete pathname of the bitmap file, prefixed with the character
\'@\'.  The returned value can be used to configure the -bitmap
option of the TK and Tix widgets.'
