-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.
