/**

* 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).
