Support for computation of the cartesian equation of a locus (if
algebraic)

lowering tolerance when solving cubic equations; this becomes
important when trying to recover the cartesian equation from
a cubic locus.

Fixed bug in "valid" method for Coordinates (used "abs"
instead of "fabs"): as a result an invalidCoordinate
was actually tested as "valid".

patched bug 157736 (not ideal, but...)

Add a few objects to pykig and fix some naming errors
(by Francesca Gatti frency.gatti@gmail.com)

Implementation of cubic-line intersections when
exactly one intersection point is already present
(by Francesca Gatti frency.gatti@gmail.com)

CubicLineOtherIntersection (by Francesca Gatti),
use special construction when intersecting a line with
a cubic in case two of the three intersections are 
already there (similar to what is done for conics)

Pass the coordinate of bottom-left corner of the text label, as XFig wants.

CCBUG: 153629

Euclidean grid:
- extend its drawing so it covers the whole visible area
- use the same grid scale (the smallest one) for x and y steps

CCBUG: 154814

Cabri1.0:
- improve parsing of objects, parsing (not reading) Formula and AngVal objects correctly
- fill the argument vector so we can construct text labels with arguments
- start reading Eq/Co objects
based on a patch provided by Maurizio.

Cabri1.2:
- improve parsing of objects, should catch more cases now

Improve the detection of the Cabri "magic", so we can try to read Cabri 1.4 constructions as 1.2.

allowing for spaces after commas in some lines of cabri save files (version 1.0)

fix some memory leaks

Improve the compatibility with Cabri1.0:
- read object names
- read Text objects (though, the arguments are untested)
- recognize a font line when present (not used at the moment)
- handle angles correctly
improve the internal readText() function.

If the loading of the document fails, completely cleanup ourselves to be able to open a new document in the same (untouched) window.

addition of a simple existence test of an object.

slightly bump up version to 0.90.1

solved a bug involving locus construction and numerical/boolean labels

added a couple of tips of the day

Added the possibility for the user to recall the last construction
by pressing the key 'Z'

add basic methods for polygons in python scripting;
also move computation of perimeter and area from
properties to methods (no difference for the user)

python 2.5 support

When drawing an ellipse, close its path so it looks like an ellipse.

Export sane sizes for circles.

Do not export lines of garbage to the LaTeX file.

Do not silently convert to an encoding different than UTF-8 when saving.

CCBUG: 135564

added construction of a conic arc by 5 points.

Fixed graphical selection of conic arcs (it didn't work correctly)

changes in ConicArcBCTP type, draw preliminary just after
center selection.  ConicArcBTPC is obsoleted.

avoid an assert that fails when constructing a conic arc with
two passing point that are symmetric with respect to the center.
(data is invalid in this case, but should not crash kig!)

Add property "center of a conic"

Typo fix.

CCBUG: 135291

correctly sets the document as modified when editing a script

replacing the "by-construction" "isPointOnCurve" for the measure transport
with the numerical test "containsPoint".  This is motivated by deficiencies
of the "by-construction" test.

implement argument list for scripts as std::list instead of
std::set (not to lose the argument ordering)

Forwardport SVN commit 556679 by binner:
fix duplicate parameter name

always give a return value so gcc won't complain

missing I18N_NOOP

Polygon-polygon intersection

Forwardport:
SVN commit 515281 by mueller:

the usual "daily unbreak compilation"

port the Edit Type dialog to KDialogBase, as it's already done in trunk

Add the possibility to change the font of a label.

Rename the "Set Size" popup menu item to the more appropriate "Set Pen Width".
CCBUG: 122445

Do not show the Style and the Size submenus in the object popup if the selection
contains only labels.
CCBUGS: 122381, 122382

Commit here too the new icons for the Numeric label by Danny Allen

Improve the selection of circles.

Draw the vector arrow with a normal style.
CCBUG: 122285

SVN_SILENT update here too

Toggling the button after showing the wizard.

Adding the support for editing a Python script.
It's possible to start the diting by right-clicking on an object created by a
script and then selecting Edit Script.
It includes full undo/redo support.

documenting a hard to sort-out compilation problem

Big refactoring of the Cabri filter.
The main changes affect the reader part, that was moved in a own class. Every
class that inherits it represent a reader for a particular Cabri version. Before
we supported (partially) only Cabri 1.0, now most of the basic objects of Cabri
1.2 are read correctly. As a result of this refactoring, a pair of objects of
Cabri 1.0 are loaded correctly.
Still some issues remain, like: support for objects which have a syntax
different from "normal" ones (for example the Compass, the Vector Sum and the
Regular polygons); the intersections need some more loving.
Added a filter status file for the Cabri filter.

Some improvements in the filters:
-) DrGeo import filter
Import some new objects, mainly because Kig supports numeric labels.

-) KSeg import filter
Import some new objects, mainly because Kig supports numeric labels.

-) XFig exporter
Added support for exporting polygons.

-) Image exporter
Before attempting opening a file for writing, check that the current file name
represents a supported image type.

Allow saving UseText and SelectStatement in macros.kigt if the original kigt file
had them.

message change

Small changes.

Invalidate intersections of a conic with a segment/ray
if it falls on the support line but outside of the
segment/ray

Bump the version of the kig-post-kde-3.5 branch to 0.90.0.

Special case of collinear points for CircleBTP and
ArcBTP

Added the circle-circle case to the "other intersection"
construction.

Treat creation of "other intersection" of conic with line
when just one of the intersections is already known.
circle-circle "other" intersection is still missing

oops, committed too much... restoring previous files

fix bug in contains for RayImp

Allow a python script to depend on a test-result string

Allow a TestResult to carry a boolean value.

Ability to return a string from python scripts

Construct a point with coordinates given by numeric labels

Allow measure transport to transport a numeric label

localize numbers in equation strings

Allow properties to be properly inherited (based on their name)
when an object dynamically changes its "Imp" type.

prettify equations strings

add a class for the handling of equations strings

Update one of the tips

normalize the cartesian equation of cubics.  This
only adds more stability, it was a minor bug

Add a new Equation class to handle (hopefully correctly) the displaying of
generic equations of max two vars.

trying out a better equation representation. For now only for
cubics.

moving in/out a couple of buttons in the toolbars

Split the TextType class in a base class and a derived class, and inherit a
NumericTextType class from the base. This new Type handles better a
NumericTextImp.
Added also a very simple construct mode to construct a numeric label, and the
way to change the value of the numeric.
Based on a patch of Maurizio, thanks! :-)

version becomes 0.11.0

A NumericTextImp has a new property to extract its
associated value.

Ooops, forgot important methods in NumericTextImp

ad hoc python script example code in the wizard depending on arguments

fixed email addresses

Move InvertibleImpType in the new special_imptypes
and clean up the special imptypes.

Moving "imptype" related stuff in a common place
(created objects/special_imptypes.*)

Remove redundancy from circle_type.cc

Now construction by center and radius can also be done
using the NumericTextImp (noti yet circle_by_center_and_diameter).
Compatibility with old kig files is preserved.  User can still
click on a segment.

Change transformations (scalings and rotation) to allow NumericTextImp
as argument

Allow a python script to depend on a NumericTextImp.

Added NumericTextImp, first step towards the possibility to
interact with numeric texts.

Since we already changed the i18n string lets also add two missing spaces

cartesian equation for cubics had arguments %1, %10m which
are too many for QString(s).

Redefinition of a label did not use the new attach method, this
caused strange behaviour and even crashes when trying to redefine
a label and reattaching it to an angle (or a polygon).

The previous patch to avoid circular recursion was buggy, this
should fix it.  Sorry.

Avoiding circular recursion when redefining a text label
(potential bug).  This completes the previous patch adding
control for the location parent also.

This fixes Bug n. 98106 (crash)

fixing a potential bug when redefining a text label

fixing a potential bug when redefining a text label

If the result of a python script is a DoubleObject (i.e. DoubleImp)
or IntObject (IntImp) also a text label containing the number is
created, thus making it possible for the user to later interact
with the script result.

A number of transformations (all the scalings and rotation) are generalized
in order to allow direct dependance on a DoubleImp (as a scaling factor
or as a rotation angle).

This change does not have any effect at the moment since the user has no
way to select a DoubleImp during construction, that possibility will be 
added in a subsequent patch

New style Circular Inversion.  Now there are only 2
ObjectType(s) for inverting points and 1D objects
respectively.  This is more general than before.

updated with vertical cubic addition

Added "vertical cubic" through 4 points (of the form y = p(x))

added "support" property for segments, rays, arcs.  It constructs
the line (resp. the circle) that contains the object.

Added support for arc of conics (this was already added in the kde4
kig version)

heavily patched method getParam in the case of locuses, it now
works much better than before, although there is still work to
be done (this is Franco Pasquarelli work)

Creating a new branch to continue improving the 3.x serie of kig.
