Re: [Printing-architecture] Common Printing Dialog: PPD extension specs updated

[Till Kamppeter <till.kamppeter@gmail.com>]

After getting some suggestions from Mike Sweet I have updated the specs 
again in some points:

- Fallback when there are no Quick Presets: Option to choose BW or color 
is "ColorModel", not "ColorMode".

- Simplified option tagging: Now the PPD contains one entry per tag. It 
defines the tag, its UI string and the options being under that tag. No 
additional lines in each option entry any more.

- Option names in tag definitions and quick preset definitions start 
with an asterisk, to clearly mark them as option names and following the 
Adobe convention where main keywords start with an asterisk.

- The CUPS options brightness, gamma, hue, and saturation are deprecated 
(will be removed from CUPS soon) and therefore they will not get 
included in the Common Printing Dialog. I have removed them from the PPD 
extensions specs.

- The CUPS options page-left, page-right, page-top, and page-bottom 
apply only to plain-text jobs. Therefore I have put them under the 
"Text" tag.

Mike, thank you very much for your help.
