+Import/Export & ImageMagick
+
+Import/Export is currently hardcoded to use ImageMagick and the RGB colormodel.
+Additionally, export is broken and even when working, only supported exporting
+to images with one layer.
+
+Kimgio is not suitable for Chalk since it only supports importing images as one 
+QImage.
+
+The new design should support plugins instead of hardcoded filters, so we can
+add an ImageMagick plugin, an openExr plugin or any other kind of image readers.
+
+Issues:
+
+        * conflicts -- more than one plugin might want to support JPEG, for instance.
+        * configuration -- compression settings, optional flattening, adding
+          profiles, colorspace conversion
+        * identification -- no sane way to distinguish a particular type of tiff from
+          another type, for instance.
+        * colormodel integration -- basically, there are cmyk, rgb and grayscale
+          images in a variety of bit depths (e.g., openexr supports 16 bit and half).
+          Colorspaces must interpret the file data to build Chalk pixels and must
+          unpack chalk pixels to a format a file exporter (e.g, ImageMagick pixel
+          packets) can work with. This means that plugins can depend on the presence
+          of other plugins.
+	* Import/export should be lossless -- i.e., all extra information any file
+	  format may attach to the image should be kept around and used on export.
+	  Examples are Exif data and profiles, but also Gimp comments.
+
+
+KisAnnotation contains metadata about an image that is grabbed from
+a file, such as exif data or TIFF tags and that we should be able to save.
