+ * Fit terminal columns and rows to the dimensions of its DOM element.
+ *
+ * ## Approach
+ *
+ *    Rows: Truncate the division of the terminal parent element height by the
+ *          terminal row height.
+ * Columns: Truncate the division of the terminal parent element width by the
+ *          terminal character width (apply display: inline at the terminal
+ *          row and truncate its width with the current number of columns).
