`viewPortPosition`	`IBoundRectNoAngle`	The physical position of the frozen rows and columns on the canvas, used for drawImage. For example, if the freezing starts from the fourth column, the left position would be 4 * column + rowHeaderWidth. The physical position means the top and left values have already considered the scaling factor.	submodules/univer/packages/engine-render/src/basics/vector2.ts:872 (opens in a new tab)
