Text.getImpl_caretShape returns strange results under certain conditions

Hi Tom,

Without a reproducible testcase it is hard to see what is happening. Are you using Text or TextFlow ?
For some reason the Text.getImpl_caretShape() seems to think the caret is in the 8th line, which seems to indicate there is some line wrapping width set when it should not (Jim just fixed a bug in that code last week).
