[386029] Use GEF4 Image instead of BufferedImage.
[NONE] Fix Ellipse.getIntersections(Line) for vertical Lines.
[NONE] Fix AbstractRectangleBasedGeometry#getShrinked(double, double, double, double).

Change the order of the parameters of the
AbstractRectangleBasedGeometry#getShrinked(double, double, double, double)
method to coincide with the #shrink(...) method.
[NONE] Fix AbstractRectangleBasedGeometry#getShrinked(double, double, double, double).
[238529] Add option to disable animation of graph layout changes
[386029] Add Color#getBlended(Color).
[386029] Add Image#toBufferedImage().

This method will most likely get removed in the near future. Although it would
be awesome if we could share image data rather than copying it.
[386029] Enhance javadoc comments.
[386029] Add ArithmeticOperations#getBlendOperation().
[386029] Add IFillMode and implementations.

Various fill operations (color-fill, gradient-fill, image-fill) are now provided
using the corresponding IFillMode implementation (ColorFill, GradientFill,
ImageFill).
[386029] Add IGraphics#draw(Point) to draw a single point.
[386029] Support IFillMode via IFillProperties.
[386029] Update tests for IFillProperties and IGraphics.
[386029] Update examples.
[386029] Change project settings to ensure a correct execution environment.
[386029] Return a copy in AbstractFillProperties#getMode().
[386029] Add GradientStop normalization in SWTFillProperties.

In order to be able to delegate the gradient drawing to SWT, a start and an end
GradientStop are inserted into the list of GradientStops if the first
user-specified GradientStop is not at a percentual distance of 0% (0.00), or the
last user-specified GradientStop is not at a percentual distance of 100% (1.00),
respectively.

SWT does only support linear single stop gradients, i.e. there may
only be a start and an end GradientStop. Therefore, if the number of
GradientStops equals 2 after normalizing, we can create an SWT Pattern
representation of the gradient.

Eventually, the normalization code will move to the GradientFill class in a
future version.
[386029] Implement repetitive ImageFill.

Add AWT support for ImageFill and update FillMode examples to show a repetitive
ImageFill.
[386029] Enhance javadoc for Color, GradientFill, and ColorFill.
[386029] Differentiate the ARGB memory layout from the RGBA color space.
