10 * ====================================================== */
15 * What advanced features the users want to do?
16 Implement them in a non latex dependent way, but a logical way.
17 LyX should translate it to latex or any other fitting format.
18 * Add a way to roll the image file into the file format.
19 * When loading, if the image is not found in the expected place, try
20 to find it in the clipart, or in the same directory with the image.
21 * Keep a tab on the image file, if it changes, update the lyx view.
22 * The image choosing dialog could show thumbnails of the image formats
23 it knows of, thus selection based on the image instead of based on
25 * Add support for the 'picins' package.
26 * Add support for the 'picinpar' package.
27 * Improve support for 'subfigure' - Allow to set the various options
33 * Current version is 1 (inset file format version), when changing it
34 * it should be changed in the Write() function when writing in one place
35 * and when reading one should change the version check and the error message.
36 * The filename is kept in the lyx file in a relative way, so as to allow
37 * moving the document file and its images with no problem.
41 * Postscript output means EPS figures.
43 * PDF output is best done with PDF figures if it's a direct conversion
44 * or PNG figures otherwise.
