	* javax/swing/plaf/basic/BasicTextUI.java
	(damageRange(JTextComponent,int,int)): Call damageRange() with
	correct biases, rather than null.
	(damageRange(JTextComponent,int,int,Bias,Bias)): Rewritten
	to use simpler modelToView() approach without much special
	casing. This seems not worth the effort and actually
	caused problems. Added locking of the document.
	* javax/swing/text/BoxView.java
	(requirementsValid): New field.
	(calculateMajorAxisRequirements): Rewritten without using
	SizeRequirements. The SizeRequirements algorithms are slightly
	different and too inefficient.
	(calculateMinorAxisRequirements): Rewritten without using
	SizeRequirements. The SizeRequirements algorithms are slightly
	different and too inefficient.
	(getAlignment): Simply return the alignment of the cached
	requirements.
	(getMaximumSpan): Add insets.
	(getMinimumSpan): Add insets.
	(getPreferredSpan): Add insets.
	(layoutMajorAxis): Rewritten without using
	SizeRequirements. The SizeRequirements algorithms are slightly
	different and too inefficient.
	(layoutMinorAxis): Rewritten without using
	SizeRequirements. The SizeRequirements algorithms are slightly
	different and too inefficient.
	(modelToView): Call setSize() rather than layout().
	(paint): Check clip for more efficient painting.
	(preferenceChanged): Invalidate requirements here.
	(replace): Invalidate requirements here.
	(updateRequirements): Update requirements only when requirements
	are marked invalid.
	* javax/swing/text/CompositeView.java
	(modelToView): Added some more checks and handling of corner cases.
	* javax/swing/text/FlowView.java
	(calculateMinorAxisRequirements): Set aligment to 0.5 and maximum
	span to Integer.MAX_VALUE. Limit preferredSize to minimumSize.
	* javax/swing/text/IconView.java
	(getAlignment): Implemented to return 1.0 for vertical alignment.
	* javax/swing/text/ParagraphView.java
	(Row.getMaximumSpan): Implemented to let Rows span the whole
	ParagraphView.
	(getAlignment): Fixed horizontal alignment and vertical alignment
	for empty paragraphs to be 0.5.

	* javax/swing/text/View.java
	(modelToView): Added special handling for corner case at the end
	of the view and for multiline views.

	* javax/swing/plaf/basic/BasicTextUI.java
	(modelToView): Read-lock the document. Set size of the
	root view before fetching the model-to-view mapping.
	(getViewIndex): Check of the position is inside the range and
	return -1 if this is not the case.
	(getViewAtPosition(int,Rectangle): Update child allocation for valid
	view index.
	(getViewIndexAtPosition(int)): Delegate the index search to
	the element since we have a 1:1 mapping between elements and
	views here.
	* javax/swing/text/DefaultCaret.java
	(appear): Ignore BadLocationException.
	(paint): Ignore BadLocationException.
	* javax/swing/text/FlowView.java
	(changedUpdate): Also notify the layoutPool view.
	(removeUpdate): Also notify the layoutPool view.
	* javax/swing/text/ParagraphView.java
	(Row.getViewIndexAtPosition): Overridden to search linearily
	through the view instead of relying on a 1:1 model to view
	mapping.
	* javax/swing/text/View.java
	(removeUpdate): Clear ElementChange object if updateChildren
	returns false.
	(forwardUpdate): Special handle some boundary cases.
