## Name

containing-aligned-viewport -- Compute the viewport-position of the viewport that contains POS.

## Synopsis

(containing-aligned-viewport pos)

## Description

Compute the viewport-position of the viewport that contains POS.
POS is a list of x and y virtual coordinates in that order. The
viewport coordinates returned will be in the same format and will be a
integral multiples of the desk size. If POS is not contained in any
valid viewport, for instance if it includes coordinates greater than
zero or greater than the desk size times the display size, the nearest
viewport will be returned instead.
