The result of applying a perspective-transform to a Bezier curve is
only an approximation. When the curve is highly nonlinear, the
result may diverge significantly from the real transformed curve.
Subdivide the curve as necessary in gimp_transform_bezier_coords()
to counter that. Adjust gimp_bezier_stroke_transform()
accordingly.
Override GimpStroke::transform() for GimpBezierStroke, using
gimp_transform_bezier_coords() to transform the stroke's segments,
so that clipping done properly.
Fix indentation, typos, style. Use array parameters for the
control points, instead of using individual by-value parameters.
Use GArray* for the results, instead of GArray**. Verify
arguments.
Adapt the rest of the code to the changes.
They are unreliable because every type checking cast discards them,
they are useless anyway, visual clutter, added inconsistently, and
generally suck. Wanted to do this a long time ago, it was a bad idea
in the first place.

* 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.

Applied patch from Alexia Death as attached to bug #471344:
* app/core/Makefile.am
* app/core/gimpcoords-interpolate.[ch]: new files with
interpolation code taken from ...
* app/vectors/gimpbezierstroke.c: ... here.
* app/Makefile.am (AM_LDFLAGS): make it link.

* app/vectors/gimpvectors.[ch]
* app/vectors/gimpstroke.[ch]
* app/vectors/gimpbezierstroke.c: Implement functionality to
get a bezier description a la moveto/curveto/closepath.
* app/vectors/vectors-types.h: implement an evil hack to avoid
the inclusion of cairo.h in most C files...
* app/vectors/Makefile.am: link against cairo
* app/widgets/gimpviewrenderervectors.c: use the new functionality
for preview rendering.

2005-12-23 Simon Budig <simon@gimp.org>
* app/vectors/gimpbezierstroke.c
* app/vectors/gimpstroke.c: shuffled some g_return*_if_fail
around as suggested by mitch.
2005-12-10 Michael Natterer <mitch@gimp.org>
* app/config/*.c
* app/core/*.c
* app/display/*.c
* app/text/*.c
* app/vectors/*.c: port to G_DEFINE_TYPE() and friends. Some related
core reordering and cleanup.
2005-10-02 Simon Budig <simon@gimp.org>
* app/vectors/gimpbezierstroke.c: fixed the bogus snaps. One
should not calculate tangents for points beyond the end of the
array...
2005-10-02 Simon Budig <simon@gimp.org>
* app/vectors/gimpbezierstroke.c: a segment doesn't necessarily
have a matching tangent. Check for this when iterating over all
segments of a path...
* app/vectors/gimpstroke.c: fix the dispatch of
_nearest_intersection_get().
2005-10-02 Simon Budig <simon@gimp.org>
* app/core/gimpcoords.c: use ABS instead of fabs.
* app/core/gimpimage-snap.c: Use proper default values for the
coordinates.
* app/vectors/gimpbezierstroke.c: Fix a bug plus add some debug
output. For some reason does not snap yet.
2005-10-01 Simon Budig <simon@gimp.org>
* app/core/gimpcoords.[ch]: Added small utility function for the
manhattan metric.
* app/vectors/gimpstroke.[ch]: virtualized stubs provided by mitch
* app/vectors/gimpbezierstroke.c: Reworked some internal functions
to make it easier to access the parameters for the coordinates of an
stroke interpolation. Simplified the straight line test. Added an
implementation of the _nearest_tangent_get () function that does
not yet seem to work properly. Not sure where the problem is.
2004-08-22 Simon Budig <simon@gimp.org>
* app/vectors/gimpbezierstroke.c: Implemented the ellipse basic
shape differently to avoid possible rounding issues with
the _arcto () command.
* app/vectors/gimpvectors-import.c: properly close the rounded
rectangles.
2004-08-21 Sven Neumann <sven@gimp.org>
* app/vectors/gimpbezierstroke.c (gimp_bezier_stroke_arcto): fixed
a bug I introduced with my last commit.
* app/vectors/gimpvectors-import.c: added support for the basic
SVG shape "rect". Fixed handling of SVG lengths in basic shapes.
2004-08-21 Sven Neumann <sven@gimp.org>
* app/vectors/gimpbezierstroke.[ch]: added new function
gimp_bezier_stroke_new_ellipse() that provides a simple API to
create a bezier stroke that represents an ellipse.
* app/vectors/gimpvectors-import.c: added support for the basic
SVG shapes "circle" and "ellipse".
2004-06-19 Sven Neumann <sven@gimp.org>
* app/vectors/gimpbezierstroke.c (arcto_ellipsesegment): moved
array initialization out of variable declaration (bug #144632).
2004-06-19 Sven Neumann <sven@gimp.org>
* app/vectors/gimpbezierstroke.c (arcto_ellipsesegment): use
G_SQRT2 to make circlemagic a constant value so we can initialize
the array on declaration. Fixes bug #144632.
2004-05-24 Michael Natterer <mitch@gimp.org>
* app/vectors/Makefile.am
* app/vectors/gimpcoordmath.[ch]: removed...
* app/core/Makefile.am
* app/core/gimpcoords.[ch]: ...and added without the "bezier"
namespace.
* app/vectors/gimpbezierstroke.c: changed accordingly.
* app/Makefile.am: force it to link gimpcoords.o
2004-03-10 Simon Budig <simon@gimp.org>
* app/base/cpu-accel.c
* app/display/gimpdisplayshell-dnd.c
* app/tools/gimpvectortool.c
* app/vectors/gimpbezierstroke.c
* app/vectors/gimpvectors-import.c: Removed, disabled or
conditionalized some debug output.
There still is debug output when pushing/popping the move tool
via space bar. Mitch wanted to look at that.
