[Tkinter-discuss] Canvas.postscript() fails to render some fonts properly

[Firat Ozgul]

Hello,

Unfortunately there are not enough documentation about Python-tk postscript
manipulation. Information is scattered here and there.

A sample code could be like this:

> canvas .c -width 300 -height 300 -bg white
> pack .c
> set fonty [font create -family "comic sans ms" -size 16]
> .c create text 20 20 -font $fonty -text "ich wollt ich waer ein huhn"
> -anchor nw
> set fontMap($fonty) [list "comic sans ms" 16]
> update idletasks
> .c postscript -file "~/test.ps" -fontmap fontMap

> However this produces an obviously broken postscript file that cannot be
