* Fit terminal columns and rows to the dimensions of its

*
* 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)
