Sometimes, some text in a metafile I display from my 
application comes up in the wrong font. The file 
displays properly in xyz Graphics program. Why?

The VCL simply wraps standard Windows functions for 
displaying metafiles. As the metafile is scaled, the 
font width and height are scaled as well. Many times, 
the Windows font mapper will simply substitute a 
different font that the font that was originally selected
in an attempt to satisfy the request. This can also be 
seen in many graphics programs if you arbitrarily scale 
the metafile in different directions. Note that some 
"hi end" graphic programs actually read the metafile 
record by record, bypassing the WIndows GDI entirely to
overcome the effects of the Windows font mapper.
