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.
(cherry picked from commit 33e47c85a2)
In GimpCurveView, when holding down Ctrl while adding/dragging a
point, snap the y-coordinate to the original curve (at the start of
the drag). This is particularly useful for adding points along the
curve, without changing their y-coordinate.
Likewise, have the coordinate indicator show the snapped
coordinate.
(cherry picked from commit 8357c9ad64)
In GimpCurveView, when dragging an existing curve point, don't
immediately move the point to the cursor position uppon button
press, but rather move it relative to its current position as the
cursor moves. This allows selecting a point without moving it, and
adjusting its position more easily.
Additionally, when the cursor hovers above a point, or when
dargging a point, have the coordinate indicator show the point's
position, rather than the cursor's.
(cherry picked from commit 0b9737a3ed)
and redo how the curves tool sets its curves in order to support this
without code duplication. Also change the color of the yellow curve in
the dynamics output editor to orange because yellow is hardly visible.

* 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/widgets/gimpcurveview.[ch]: port internal cursor stuff to
gdouble, fix off-by-one in curve drawing, fix drawing artefact in
handle drawing by starting drawing on the handle's outline and not
its center.

* app/widgets/gimpcurveview.[ch]: port the "xpos" API
to [0.0..1.0] doubles too.
* app/tools/gimpcurvestool.[ch]: rename "col_value" member to
"picked_color" and use gdouble instead of gint. Also use GimpCurve
API to map the values instead of accessing the curve directly.
Fixes setting curve anchor points by color picking.

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.

* app/widgets/gimpcurveview.[ch]: draw a base-line with the
grid.
Not sure if this should stay enabled for the Curves tool...

2007-11-09 Sven Neumann <sven@gimp.org>
* app/widgets/gimpcurveview.[ch]: added construct-only
properties
to control the number of grid rows and columns. Increased the
default values to 8.

2007-11-05 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpcurveview.[ch]: added event handling and
completely edit the curve here.
* app/tools/gimpcurvestool.[ch]: remove all event handling and
curve editing code and only listen to curve signals.

* app/widgets/Makefile.am
* app/widgets/widgets-types.h
* app/widgets/gimpcurveview.[ch]: new GimpHistogramView subclass
which does all the curve stuff.
* app/widgets/gimphistorgramview.[ch]: removed all curve code again.
* app/tools/gimpcurvestool.c: changed accordingly.
