SVG parsing is now done by XML::LibXML::Reader, if available,

comment) chunk (RT #28054)

for outdated Perl versions. If you need it to run on 5.005, write
a patch and file a bug report please.)

* add interlace.png and beef up t/png.t
2006-05-01 v1.21 Tels 96 tests

* reducing test.jpg with GIMP reveals a bug in EXIF parsing (not yet fixed)
* MakerNote parsing:
+ add support for Panasonic cameras
+ for the following manufacturers we do not check the camera model, this
gets all cameras, even yet unreleased ones to work:
+ Canon
+ Panasonic
+ Casio
+ Olympus
+ Fujifilm

trailing \x00 chars, so we remove them and set the correct length
