[cp-patches] Patch: Text fix

[Lillian Angel]

This fixes several assertion error and NPES found. Lots of functions
were not implemented according to the API. This is now fixed to work
like the JDK.

        Fixes PR classpath/PR24721
        * javax/swing/text/BoxView.java
        (getViewAtPoint): Added check in to return the last view, 
        if one exists and the point was not contained in the rectangle. 
        This is what the JDK does.
        * javax/swing/text/CompositeView.java
        (viewToModel): Fixed API documentation. Added check to make sure
        x and y are greater than 0. Otherwise, 0 is returned.
        * javax/swing/text/DefaultCaret.java
        (moveDot): Added check to match API specs.
        (setDot): Likewise.
        * javax/swing/text/GlyphView.java
        (viewToModel): Removed assert. This is not needed here. The 
        point does not need to be in the rectangle.
