[gs-code-review] CET 23-13-04, Font dictionary differences

[Alex Cherepanov]

Require resource category to be a name in the findresource operator.
Convert 1st operand to a name when it's a string.
Partly fix CET 23-13-04.

Differences:
None: no CET or comparefiles differences.

The content of Courier font directory is still different.
Ghostscript has /.Alias and /PathLoad
Tek has /FontType 14, /CharOffsets, /GlyphData
Distiller 5 has /CharOffsets, /DistillID
PhotoPrint has /CharOffsets

The values of UniqueID, XUID, the length of CharStrings and Private
is different too.

Please review my decision to consider there differences as acceptable.

Alex,

The mentioned font dictionary keys are not important
because PLRM reads that implementations may add
specific keys to font dictionary.
Please close with AOK and appropriate comment.

Leo.
