Tor Lillqvist cfab7a9aa3 The stat() function in the Win32 C runtime doesn't like if directory names 
2000-04-11  Tor Lillqvist  <tml@iki.fi>

* libgimp/gimpenv.c (gimp_path_get_user_writable_dir): The stat()
function in the Win32 C runtime doesn't like if directory names
have an extra G_DIR_SEPARATOR suffixed. Remove such before calling
stat(). Those extra (back)slashes are added by for instance
gimp_path_parse(). Document that feature of gimp_path_parse().

* libgimp/gimputils.c (gimp_strescape): Correct documentation for
gimp_strescape(). The semantics of the exceptions parameter was
documented backwards. Clarify what the function does.

* plug-ins/gfig/gfig.c (plug_in_parse_gfig_path)
* plug-ins/FractalExplorer/FractalExplorer.c
(plug_in_parse_fractalexplorer_path)
* plug-ins/gflare/gflare.c (plug_in_parse_gflare_path,
gflare_save): Use painstakingly correct platform-specific
directory and search path separators, and escaped with
gimp_strescape when displayed as part of a gimprc entry.

* app/gimphelp.c: No debug messages on Win32, thanks.

	GFlare plug-in ver 0.25

		Eiichi Takamori <taka@ma1.seikyou.ne.jp>

==========================================================================

  GFlare is a plug-in for the GIMP.  The name "GFlare" is short for
"Gradient Flare".  It renders lense flare effect using custom
gradients.  The basic idea is suggested by Marcelo Malheiros,
originally based on a 3DStudio MAX plug-in called LenZFX:
	http://www.digimation.com/techsupp/lzfxfeat.htm

INSTALL:

1) Edit Makefile, if needed.

2) Type "make install".

3) Type "make install-data" if needed. (It copies sample gradients and
   gflares under ~/.gimp)

3) Add new entry to ~/.gimp/gimprc as
     (gflare-path "${gimp_dir}/gflares:${gimp_data_dir}/gflares")

3) Run the GIMP. The menu path is <Image>/Filters/Effects/GFlare.


HOW TO USE IT:

  The document is not yet done. Try and see.

  Main Dialog:
  - Preview
      click on it changes the position of GFlare
  - Settings page
    - Center, Radius (pixel), Rotation (degree), Hue Rotation (degree)
    - Vector Angle (degree) and Vector Length (percentage to Radius)
    - adaptive supersampling ... same as "Blend tool"
  - Selector page
    - ListBox
    - New, Edit, Copy, Delete buttons. Edit button invokes GFlare Editor.

  GFlare Editor:
  - General page:
  - Glow page:
  - Rays page:
  - Second Flares page:     

  WARNING: This plug-in is in development stage, and the code is very
alpha. The GFlare datafile format may be changed in future version.

  Suggestions and ideas for user interface, flare algorithm, etc. are
very welcome.


KNOWN BUGS:

  There are still lots of bugs, of course. ;-)
  They seem related to GTK, and I don't know exactly how I can fix them.

  * It warns at startup as:
    ** WARNING **: file gdkwindow.c: line 422 (gdk_window_move_resize): "window != NULL"
    If you are annoyed, accompanying "gtkviewport.c.patch" will shut up
    the warning.
  * Edit button remains prelighted when GFlare Editor dialog is done.
  * Dialogs are not shown quickly at startup.
  * Sometimes note tab labels are disappeared.
  * Sometimes it crashes, but I don't know yet why it happens.

TODO:
  * Random hue scattering for Second Flares.
  * Improve internal gradients.
  * Currently number of Second Flares is fixed(30).
  * Change opacity for one second flare dynamically, in inverse
    proportion to the size of it.
  * Reduce dialog size
  * Add tweak ability "How to combine Glow, Rays, Second Flares in
    what order"


CREDITS:

  Marcelo Marheiros and Federico Mena Quintero suggested a lot of
ideas. Very Thanks!!

  Marcelo made gradients whose names end with _1, _2, etc. The
gradients whose names end with _101, _102 etc. are mine.

  Quartic did awful Gradient Editor, and gradients PDB procedures.

  A fair proportion of this code was taken from:
