Revision history for Perl extension PostScript::File.

2.10   May 5, 2011
	API improvements:

	- You can pass "newpage => 0" to the constructor to prevent it
	  from creating the first page.	 This leads to more natural
	  loops, because you call newpage before each page (instead of
	  "before each page except the first").
	- Added get_printable_width, get_printable_height,
	  get_page_printable_width, & get_page_printable_height methods

	- Fixed bug: clipping never actually worked
	- Fixed bug: errx parameter was not handled correctly in new
	- Documentation fixes

2.02   December 24, 2010
	- Revised the rules for hyphen-minus processing:
	  If it's preceded by punctuation and followed by a digit, or
	  it's followed by a currency symbol, it's a minus sign (U+2212).
	- Clean up use of eval and properly localize $@

2.01   March 3, 2010
	- The metrics for the cp1252 encoding did not reflect the
	  accents mapped to control characters (but those characters
	  are not normally used, anyway).
	- Fixed some warnings in the test suite
	- Version 2.00 actually needs Encode 2.21, but only specified 2.12

2.00   February 26, 2010
	- Numerous API changes, mostly minor, but there could be
	  problems with backwards compatibility.

	- Changed ISOLatin1Encoding to match PostScript's
	  The HYPHEN-MINUS (\x2D) is now /minus instead of /hyphen.
	  Use SOFT-HYPHEN (\xAD) to get a proper hyphen.
	  Made the same change to Win1252Encoding (cp1252).

	  Please read Hyphens and Minus Signs in PostScript::File for details.

	- Added auto_hyphen attribute with get/set methods
	- Added need_fonts attribute
	- Added as_string, embed_font, need_resource, & testable_output methods
	- add_resource accepts all DSC 3.0 resource types,
	  but no longer accepts generic 'Resource' type
	- Reencode fonts added using embed_font or add_resource
	- Added PostScript::File::Metrics, which includes the metrics
	  for the standard PostScript fonts.  No more trying to
	  configure Font::AFM!!!
	- PNG output has been removed.  Use PostScript::Convert instead.
	- embed_document now handles & removes TIFF, WMF, or EPSI preview
	- output accepts an open filehandle as a filename alternative
	- Passing undef to output always returns the PostScript as a string

	Minor changes in 2.00:

	- Don't reencode Symbol; it doesn't use the StandardEncoding.
	  This is not backwards compatible, but I doubt anyone was
	  using Symbol-iso, as it's not very useful.
	- Mapped some control characters as accents in Win1252Encoding,
	  since the Red Book suggests they are required in langlevel 1
	- add_default, add_resource, add_setup, add_page_setup,
	  add_page_trailer, & add_trailer now append instead of
	  overwriting previous value
	- add_function is now a no-op if has_function returns true
	- add_resource uses BeginResource instead of deprecated comments
	- get_strip now returns 'none', 'space', or 'comments'
	  instead of the regular expression being used
	- In eps mode, output now returns a list of pages
	- Multiple calls to output no longer cause duplicate resources
	- Passing a filename to output does not permanently set the filename
	- Fonts & resources appear in the document Setup section
	  instead of the Prolog
	- Include a Local Variables section for Emacs in the %%Trailer
	  describing the file's encoding

1.05   October 29, 2009
	- Major change in the way reencode works
	  Setting it to 'cp1252' or 'iso-8859-1' causes automatic
	  character set translation from Unicode strings.
	- Added cp1252 (Win1252Encoding) support
	  Most people should now use reencode => 'cp1252',
	  even if they are not on Windows, to get the best
	  Unicode support (which is still quite limited).
	- When writing to a file, the output method now returns the pathname
	- The %%BoundingBox must be integers.  If it's not, round up and
	  also add a %%HiResBoundingBox comment.
	- Fixed bug in pstr (wasn't quoting backslashes)
	- It's %%PageOrder, not %%Order (and the order should be capitalized)
	- Added an examples directory

1.04   October 22, 2009
	- add_comment now appends to comments (as originally documented)
	  (fixes RT#25786)
	- Allow WIDTHxHEIGHT as a paper size
	- Remove spaces before DSC comments even when strip none
	- pstr now wraps strings longer than 240 characters
	- strip comments is more aggressive (but won't remove DSC comments)

1.03   October 20, 2009
	- Added pstr function/method
	- Added embed_document method
	- The dir & file parameters to new now actually work
	- The file_ext parameter and {get,set}_file_ext methods allow
	  you to change the way PostScript::File appends an extension
	  to the output filename
	- The PNG output added in 1.01 is now documented
	- Using Ghostscript to generate PNG should work on Windows now
	- Include resource types in %%DocumentSuppliedResources comment
	- Fixed has_function to avoid false positives
	- Include procset PostScript_File in %%DocumentSuppliedResources
	- PostScript::File now requires Perl 5.8.0 or later

1.02   September 21, 2009
	- Now maintained by Christopher J. Madsen
	- Stripping leading whitespace now works with Perl 5.10 (RT#49838)
