[McIDAS #MGZ-769333]: PTDISP Letter size

Very good.

Hmm... I think that the cause of the size jump is "quantization" of
the fonts.  Consider:

<as 'mcidas'>
cd ~mcidas
cat -alt data/NEWMR.FFD

-Adobe-New Century Schoolbook-Medium-R-Normal-
none                             1

none                             3
none                             4

ncenR10.bdf                      11
ncenR12.bdf                      12
ncenR12.bdf                      13
ncenR14.bdf                      14
ncenR14.bdf                      15
ncenR14.bdf                      16
ncenR18.bdf                      17
ncenR18.bdf                      18
ncenR18.bdf                      19
ncenR18.bdf                      20

You can see that the actual size used for the McIDAS-specified sizes of
6-8 is 8, 9-11 is 10, 12-13 is 12, etc.

I would guess (and it is purely a guess) that there could be a non-jumpy
gradation is font sizes of the corresponding '.bdf' (Glyph Bitmap Distribution
Format) file was available and the corresponding FFD file "pointed" to the
correct file for each McIDAS-specified size.

McIDAS-X is distributed with a finite number of FFD and bdf files.  I guess
that SSEC did this for some good reason, but I don't know for sure.

Cheers,

Tom
