+How to use it for now:
+ * The lyxfunc 'graphics-insert' will insert this inset into the document.
+*/
+
+/*
+Immediate tasks:
+ * Make the inline viewing work, there is a preliminary work going on,
+ need to finish it up.
+
+ * Polishing tasks:
+ * Add messages in the empty rectangle to say how are we doing.
+ - Implemented, needs testing.
+ * Clean up GraphicsCacheItem(_pimpl)
+ * Pop up a dialog if the widget version is higher than what we accept.
+ * Prepare code to read FigInset insets to upgrade upwards
+ * Provide sed/awk/C code to downgrade from InsetGraphics to FigInset.
+
+*/
+
+/*
+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.
+ * Bug in FileDlg class (src/filedlg.[hC]) when selecting a file and then
+ pressing ok, it counts as if no real selection done. Apparently
+ when choosing a file it doesn't update the select file input line.
+ * Inline viewing is still not completely operational, in fact it is no
+ disabled. To enable it enable the define:
+ INSETGRAPHICS_INLINE_VIEW
+
+Current PROBLEMS:
+
+ * How to support both PDF and PS output, should we do the conversion
+ or should we just give the bounding box and tell latex how to do the
+ conversion itself?
+ I (Baruch Even) tend towards doing the conversion ourselves, otherwise
+ we need to give latex quite a few translation commands and from the
+ graphicx package docs it appears that it takes quite a bit of memory
+ on the side of TeXing.
+
+TODO Basics:
+
+ * Add support for more features so that it will be better than insetfig.
+ * Keep aspect ratio radio button
+
+ * Work on inline viewing of image.
+
+TODO Before initial production release:
+ * Replace insetfig everywhere
+ * Read it's file format
+ * Get created by all commands used to create figinset currently.
+ * Search for comments of the form
+ // INSET_GRAPHICS: remove this when InsetFig is thrown.
+ And act upon them.
+
+ * Finish the basic To-do list.
+ * Extract the general logic of the dialog in order to allow easier porting
+ to Gnome/KDE, and put the general logic in frontends and the inherited
+ platform dependent code in the appropriate dirs.
+
+TODO Extended features:
+
+ * Advanced Latex tab folder.
+ * Add even more options to make it better than insetfig.
+ * Support for complete control over the latex parameters for TeXperts
+ * 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:
+ *
+ * Intentions:
+ * This is currently a moving target, I'm trying stuff and learning what
+ * is needed and how to accomplish it, since there is no predefined goal or
+ * way to go I invent it as I go.
+ *
+ * My current intention is for seperation from LaTeX, the basic needs are
+ * resizing and rotating, displaying on screen in various depths and printing
+ * conversion of depths (independent of the display depth). For this I'll
+ * provide a simple interface.
+ *
+ * The medium level includes clipping of the image, but in a limited way.
+ *
+ * For the LaTeX gurus I'll provide a complete control over the output, but
+ * this is latex dependent and guru dependent so I'd rather avoid doing this
+ * for the normal user. This stuff includes clipping, special image size
+ * specifications (\textwidth\minus 2in) which I see no way to generalize
+ * to non-latex specific way.
+ *
+ * Used packages:
+ * 'graphicx' for the graphics inclusion.
+ * 'subfigure' for the subfigures.
+ *
+ * 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:
+ *
+ * Apparently the PNG output is preferred over PDF images when doing PDF
+ * documents (i.e. prefer imagemagick eps2png over eps2pdf)
+ */
+
+/* Current Stage:
+ * Embryonic.
+ *
+ * PLAN:
+ * Finish basic support:
+ * Inline image viewing
+ *
+ * Do Release quality support:
+ * Allow to change display depth
+ * Make default figure instead of InsetFig
+ * Add to LyX (probably after 1.1.6 is released)
+ *
+ * Extended features:
+ * Output format conversion
+ * Print depth changes
+ * Image file tracking of changes.
+ *
+ * Extended^2:
+ * Image roll-in (how? when? why?)
+ * This means to add the image inside the LyX file, usefull when
+ * transferring the file around.
