Another observation, and it may be a different issue.  If i try to insert a Text instance with -fx-scale-x:200% into the flow, the scale affects the glyph rendering but neither caretShape, preferredWidth, nor hitInfo:


                t("BOLD ", f, "-fx-font-weight:bold;"),
                t("BOLD ", f, "-fx-font-weight:100; -fx-scale-x:200%;"),
                t("BOLD ", f, "-fx-font-weight:900;"),
