+Known BUGS:
+
+ * If the image is from the clipart, and the document is moved to another
+ directory, the user is screwed. Need a way to handle it.
+ This amounts to a problem of when to use relative or absolute file paths
+ We should probably use what the user asks to use... but when he chooses
+ by the file dialog we normally get an absolute path and this may not be
+ what the user meant.
+ [Note that browseRelFile in helper_funcs.* provides a file name
+ which is relative if it is at reference path (here puffer path)
+ level or below, and an absolute path if the file name is not a
+ `natural' relative file name. In any case,
+ MakeAbsPath(filename, buf->filePath())
+ is guaranteed to provide the correct absolute path. This is what is
+ done know for include insets. Feel free to ask me -- JMarc
+ 14/01/2002]
+
+ * If we are trying to create a file in a read-only directory and there
+ are graphics that need converting, the converting will fail because
+ it is done in-place, into the same directory as the original image.
+ This needs to be fixed in the src/converter.C file
+ [ This is presumed to be fixed, needs testing.]
+
+ * We do not dither or resize the image in a WYSIWYM way, we load it at
+ its original size and color, resizing is done in the final output,
+ but not in the LyX window.
+
+TODO Before initial production release:
+ * Replace insetfig everywhere
+ * Search for comments of the form
+ // INSET_GRAPHICS: remove this when InsetFig is thrown.
+ And act upon them. Make sure not to remove InsetFig code for the
+ 1.2.0 release, only afterwards, after deployment shows InsetGraphics
+ to be ok.
+ * What advanced features the users want to do?
+ Implement them in a non latex dependent way, but a logical way.
+ LyX should translate it to latex or any other fitting format.
+ * Add a way to roll the image file into the file format.
+ * When loading, if the image is not found in the expected place, try
+ to find it in the clipart, or in the same directory with the image.
+ * Keep a tab on the image file, if it changes, update the lyx view.
+ * The image choosing dialog could show thumbnails of the image formats
+ it knows of, thus selection based on the image instead of based on
+ filename.
+ * Add support for the 'picins' package.
+ * Add support for the 'picinpar' package.
+ * Improve support for 'subfigure' - Allow to set the various options
+ that are possible.
+ */
+
+/* NOTES:
+ * Fileformat:
+ * Current version is 1 (inset file format version), when changing it
+ * it should be changed in the Write() function when writing in one place
+ * and when reading one should change the version check and the error message.
+ * The filename is kept in the lyx file in a relative way, so as to allow
+ * moving the document file and its images with no problem.
+ *
+ *
+ * Conversions:
+ * Postscript output means EPS figures.
+ *
+ * PDF output is best done with PDF figures if it's a direct conversion
+ * or PNG figures otherwise.
+ * Image format
+ * from to
+ * EPS epstopdf
+ * PS ps2pdf
+ * JPG/PNG direct
+ * PDF direct
+ * others PNG
