CellSelection

data class CellSelection(val anchorColumn: Int, val anchorRow: Int, val caretColumn: Int, val caretRow: Int, val isBlock: Boolean = false)

Half-open terminal cell selection in visible render-cache coordinates.

anchorColumn and anchorRow identify the fixed selection edge. caretColumn and caretRow identify the moving edge and may be before the anchor for backward selections. Columns are caret positions between cells, so selecting cells 2 through 4 on one row is represented as columns 2..5.
