Allow setting the type of GimpCurve control-points to either SMOOTH
or CORNER. Smooth points produce a smooth curve, while corner
points produce a sharp curve (previously, all points were smooth).
In GimpCureView, display corner points using a diamond shape,
instead of a circle.
In the Curves tool, allow changing the curve's point types.
In GimpCurve, replace the use of a fixed-length control-point array
with a dynamically-sized array. Adapt GimpCurve's interface, and
the rest of the code.
In addition to simplifying the code, this fixes a bug where the
curve object could be broken by moving the mouse too fast (yep...),
and allows more accurate point placement, both in the GUI editor,
and through canvas interaction in the Curves tool (see issue #814).

* all files with a GPL header and all COPYING files:
Change licence to GPLv3 (and to LGPLv3 for libgimp).
Cleaned up some copyright headers and regenerated the parsers in
the ImageMap plugin.

* app/core/gimpcurve.[ch]: keep a boolean flag to identify an
identity mapping. Set it to TRUE when the curve is reset.
* app/core/gimpcurve-map.c (gimp_curve_map_value): optimize for
the case where the curve is an identity mapping.

2008-05-11 Sven Neumann <sven@gimp.org>
* app/core/gimpcurve.[ch]: renamed gimp_curve_map() to
gimp_curve_map_value(). Added new function
gimp_curve_map_pixels()
which will allow for better optimization.
* app/gegl/gimpoperationcurves.c
(gimp_operation_curves_process):
use gimp_curve_map_pixels().
* app/tools/gimpcurvestool.c
* app/widgets/gimpcurveview.c: follow API change.

2008-02-28 Michael Natterer <mitch@gimp.org>
* app/core/gimpcurve.[ch]: get rid of fixed-size arrays and
allocate the points and curve arrays dynamically. Added "n-points"
and "n-samples" CONSTRUCT_ONLY properties. Renamed member "curve"
to "samples". Lots of code changes to work with dynamic limits
rather than 17 and 256.
* app/core/gimpdrawable-curves.c
* app/gegl/gimpcurvesconfig.c
* app/tools/gimpcurvestool.c
* app/widgets/gimpcurveview.c: changed accordingly.
svn path=/trunk/; revision=24995
2008-02-11 Michael Natterer <mitch@gimp.org>
* app/core/gimpcurve.[ch]: add gimp_curve_get_point().
* app/gegl/gimpcurvesconfig.c
* app/widgets/gimpcurveview.c: use it instead of accessing the
points array directly.
svn path=/trunk/; revision=24857
2008-02-09 Michael Natterer <mitch@gimp.org>
* app/core/gimpcurve.[ch]: keep the anchor points as an array of
GimpVector2 instead of plain doubles.
* app/gegl/gimpcurvesconfig.c
* app/widgets/gimpcurveview.c: changed accordingly.
svn path=/trunk/; revision=24842
2008-02-09 Michael Natterer <mitch@gimp.org>
* app/core/gimpcurve.[ch]: changed all values to be [0.0..1.0]
doubles instead of [0..255] integers. Also changed the API to use
doubles instead of ints. Still have the fixed-size arrays though.
(gimp_curve_map): new function to map values.
* app/gegl/gimpoperationcurves.c: remove private map() function
and use the one from GimpCurve.
* app/gegl/gimpcurvesconfig.c
* app/core/gimpdrawable-curves.c: port to the new gdouble API.
* app/tools/gimpcurvestool.c: use gimp_curve_get_uchar() to get
the arrays for the color bars.
* app/widgets/gimpcurveview.[ch]: port to gdouble and some cleanup.

2007-11-05 Michael Natterer <mitch@gimp.org>
* app/core/gimpcurve.[ch]: don't recalculate the curve if the data
object is frozen. Recalculate on thaw instead. Made
gimp_curve_calculate() private and emit some GimpData::dirty
signals where appropriate.
* app/tools/gimpcurvestool.c
* app/widgets/gimpcurveview.c
* tools/pdbgen/pdb/color.pdb: changed accodingly (connect to "dirty"
instead of "notify" and added some freeze/thaw where approproate).
* app/pdb/color_cmds.c: regenerated.
svn path=/trunk/; revision=24063
2007-11-02 Michael Natterer <mitch@gimp.org>
* app/core/gimpcurve.[ch]: added API to modify free-form curves
and properties to listen to curve changes.
* app/widgets/gimphistogramview.[ch]: added everything that's
needed for rendering a curve with all its color and cursor
indicators on top of a histogram. This code will move to a
subclass soon.
* app/tools/gimpcurvestool.[ch]: removed all curve rendering here.
Also removed all explicit updating by connecting to curve signals
and updating in the callback.
svn path=/trunk/; revision=24045
2007-11-02 Michael Natterer <mitch@gimp.org>
* app/core/Makefile.am
* app/core/core-types.h
* app/core/gimpcurve-save.[ch]
* app/core/gimpcurve-load.[ch]
* app/core/gimpcurve.[ch]: new GimpData subclass which keeps a
curve as known from the curves tool. Pretty much unfinished, but
can do everything that used to be done by base/curves.c and more.
* app/base/curves.[ch]: stripped down to plain arrays of
uchar (the actual curve) and the LUT setup function. All the rest
is done by GimpCurve now.
* app/tools/gimpcurvestool.[ch]: use an array of GimpCurves
instead of the old Curves cruft. Use Curves only for the last step
of creating the LUT. Pretty much unfinished migration here too.
* tools/pdbgen/pdb/color.pdb: use a GimpCurve here too.
* app/pdb/color_cmds.c: regenerated.
