[Document Systems]

This bug submitted by Howard Hoagland at www.docmagic.com based on the OpenPCL Developer Forum posts: 4323346, 4323390, 4324350, 4325460, 4325554, 4325674.

Need to implement:

1. For printer built in fonts, setting the Secondary font independently of the Primary font and without overwriting the Primary font. The PCL command is
"ESC ) s # T"
for Secondary font.
The Primary font is already being handled, which is
"ESC ( s # T"
where # is the typeface int of the printer built in font. Note the difference is the ) or the ( .

2. For soft fonts downloaded to the printer in the PCL file, assign a font ID number to be the Primary font
"ESC ( # X",
independently of assigning a font ID to be the Secondary font
"ESC ) # X",
where # is the Font ID number. Note the difference is the ) or the ( .

3. Flip between using the Primary font or the Secondary font as the current drawing font when these PCL commands are parsed from the input PCL file:
char "15" is Shift In (use Primary Font)
and
char "14" is Shift Out (use Secondary Font)
and handle whether the currently set Secondary Font is a printer built in font, or a soft font.
