Icon decorator that implements the view interface. The entire element is used to represent the icon. This acts as a gateway from the display-only View implementations to interactive lightweight icons (that is, it allows icons to be embedded into the View hierarchy. The parent of the icon is the container that is handed out by the associated view factory.

(->icon-view elem)
Constructor.
Creates a new icon view that represents an element.
elem - the element to create a view for - javax.swing.text.Element

(get-alignment this axis)
Determines the desired alignment for this view along an axis. This is implemented to give the alignment to the bottom of the icon along the y axis, and the default along the x axis.
axis - may be either View.X_AXIS or View.Y_AXIS - int
returns: the desired alignment >= 0.0f && <= 1.0f. This should be
a value between 0.0 and 1.0 where 0 indicates alignment at the
origin and 1.0 indicates alignment to the full span
away from the origin. An alignment of 0.5 would be the
center of the view. - float
Determines the desired alignment for this view along an axis. This is implemented to give the alignment to the bottom of the icon along the y axis, and the default along the x axis. axis - may be either View.X_AXIS or View.Y_AXIS - `int` returns: the desired alignment >= 0.0f && <= 1.0f. This should be a value between 0.0 and 1.0 where 0 indicates alignment at the origin and 1.0 indicates alignment to the full span away from the origin. An alignment of 0.5 would be the center of the view. - `float`
(get-preferred-span this axis)
Determines the preferred span for this view along an axis.
axis - may be either View.X_AXIS or View.Y_AXIS - int
returns: the span the view would like to be rendered into
Typically the view is told to render into the span
that is returned, although there is no guarantee.
The parent may choose to resize or break the view. - float
throws: java.lang.IllegalArgumentException - for an invalid axis

(model-to-view this pos a b)
Provides a mapping from the document model coordinate space to the coordinate space of the view mapped to it.
pos - the position to convert >= 0 - int
a - the allocated region to render into - java.awt.Shape
b - the bias toward the previous character or the next character represented by the offset, in case the position is a boundary of two views; b will have one of these values: Position.Bias.Forward Position.Bias.Backward - javax.swing.text.Position$Bias
returns: the bounding box of the given position - java.awt.Shape
throws: javax.swing.text.BadLocationException - if the given position does not represent a valid location in the associated document

(paint this g a)
Paints the icon. The real paint behavior occurs naturally from the association that the icon has with its parent container (the same container hosting this view), so this simply allows us to position the icon properly relative to the view. Since the coordinate system for the view is simply the parent containers, positioning the child icon is easy.

(view-to-model this x y a bias)
Provides a mapping from the view coordinate space to the logical coordinate space of the model.
x - the X coordinate >= 0 - float
y - the Y coordinate >= 0 - float
a - the allocated region to render into - java.awt.Shape
bias - javax.swing.text.Position$Bias[]
returns: the location within the model that best represents the
given point of view >= 0 - int
