Based on original patches from Hartmut Kuhse and modified
by Michael Natterer. Changes include:
- remove libexif dependency and add a hard dependency on gexiv2
- typedef GExiv2Metadata to GimpMetadata to avoid having to
include gexiv2 globally
- add basic GimpMetadata handling functions to libgimpbase
- add image and image file specific metadata functions to libgimp,
including the exif orientation image rotate dialog
- port plug-ins to use the new APIs
- port file-tiff-save's UI to GtkBuilder
- add new plug-in "metadata" to view the image's metadata
- keep metadata around as GimpImage member in the core
- update the image's metadata on image size, resolution and precision
changes
- obsolete the old metadata parasites
- migrate the old parasites to new GimpMetadata object on XCF load
Add an 'As Animation' toggle to the GIF export options. If checked,
the GIF will be written as an animation. Only enable it on images with
more than on layer though. Add the new GIFSaveVals as_animation member
last so we don't break gimp_get_data() of old data. The fix moves the
GIF options fetching to *before* gimp_export_image(). If as-animation,
we simply pass GIMP_EXPORT_CAN_HANDLE_LAYERS to capabilities so the
layers are kept.
To give us experience with Glade + GtkBuilder, use it for the save
dialog in the PNG plug-in. The layout is as good as
identical. Mnemonics still works and strings are still translated.
