Stable release with all changes in 1.30_50..1.30_53

Patch by Tony Hook to fix handling of PPM files with 2 bytes/sample.

2010-02-09 Slaven Rezic <slaven@rezic.de>

Release 1.30_53

Repacked because Module::Install 0.93 does not ignore xt tests. See https://rt.cpan.org/Ticket/Display.html?id=54450

2010-02-09 Slaven Rezic <slaven@rezic.de>

Release 1.30_52

2009-11-22 Slaven Rezic <slaven@rezic.de>

Release 1.30_51

Fixes in GIF reader (unknown intro codes are now only warnings, application chunks are forced into the first image data)

Added some test images for previous fixes.

2009-11-14 Slaven Rezic <slaven@rezic.de>

Release 1.30_50

Support for Microsoft .ico files (Image::Info::ICO).

Fixes in JPEG parsing (skip pad 0xFF in markers).

Fixes in GIF reader ("trailer" seems to be optional).

Somewhat better recognition of XBM files.

XPM handling: Corrected color parsing. Try harder to find X11's rgb.txt. Ignore comments in rgb.txt.

Reordered magic checks to have more common image formats first.

Introduced Bundles.

Some Pod cleanups.

Additional author tests in xt.

2009-10-31 Slaven Rezic <srezic@cpan.org>

Release 1.30

Stable release with all changes in 1.29_51..1.29_53

2009-09-23 Slaven Rezic <srezic@cpan.org>

Release 1.29_53

SVG parsing: load_ext_dtd is now set to false, to avoid unnecessary possible network connections; this is also ceasing errors with libxml 2.7.x.

2009-09-16 Slaven Rezic <srezic@cpan.org>

Release 1.29_52

More diagnostics in failing tests.
Added tests cases for RT #49546.

2009-09-14 Slaven Rezic <srezic@cpan.org>

Release 1.29_51

Fixed "substr outside of string" problem with Fujifilm FinePix S1000fd images (RT #49546)

2009-08-14 Slaven Rezic <srezic@cpan.org>

Release 1.29_50

Marked Compress::Zlib as recommended module and skip a test if it is not installed (RT #48415)

2009-07-31 Slaven Rezic <srezic@cpan.org>

Release 1.29

SVG parsing is now done by XML::LibXML::Reader, if available, otherwise the old XML::Simple-based code is used. Using the new code is much more memory efficient and faster. The old module can still be used by setting @Image::Info::SVG::PREFER_MODULE

Removed deprecation notice.

Bundled Module::Install 0.91.

Ceased a warning in the JPEG parsing code with perl 5.6.x.

Lowered minimum required Perl version to 5.6.0 (There's no evidence that it does not work with that Perl version).

Ceased warnings when reading PNG files with ztxt (compressed comment) chunk (RT #28054)

2008-03-30 v1.28 Tels 128 tests

• raise minimum required Perl version to v5.6.2 (it doesn't work on 5.005 anyway, open() with three arguments is not supported there and I don't have time to rewrite the code for outdated Perl versions. If you need it to run on 5.005, write a patch and file a bug report please.)
• fix bug #15167: Incorrect width and height for JPG files (the fix now keeps the highest value for width/height, instead of creating an array ref with all the values)
