I have two questions related to fonts in graphics. First, I have a number of
postscript fonts installed.  They appear as one would expect in the
Mathematica menu under Format->Font, and also, if I use something like

txt = StyleForm["Hello World", FontSize -> 36, FontFamily -> "AmazingFont",
FontWeight -> "Ordinary"]
then the output appears correctly (i.e., it looks right, having the correct
font) as the display value for txt. Furthermore, if I simply embrace this in
Text[] such as

Text[txt, {0,0}]

the output shows

Text[Hello World, {0,0}]

again with the text of "Hello World" being displayed within the Notebook in
AmazingFont. But when I put that Text[] into a graphic,

Show[Graphics[Text[txt,{0,0}]]]

the font is now substituted with Helvetica. I have used Ctrl-E to examine
the postscript of the graphic, which confirms the Helvetica. What am I doing
wrong, and please, how can I correct it?

The second question is a repeat of one which appeared many years ago on the
newsgroup (1992?) but received no reply at the time. It is this. Can one
interrogate the font metrics from within Mathematica so that one can
discover the dimensions of, say, the letter "i" in Helvetica font 14 point.
