* 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)
|
