Update the Val::evaluate function to support viewport coordinates #9535
Description
What problem does this solve or what need does it fill?
The evaluate method of Val needs to be updated to support Val's viewport variants.
What solution would you like?
Val evaluate and all of Val's _with_size functions that use evaluate will need a viewport size parameter.
Viewport coordinates are explained here.
The tests also need to be updated and expanded to cover the viewport variants.
