When using the input fields to resize the sign language window, two odd things happen:

1. The aspect ratio calculations give the wrong number for height when calculation proportions.
2. The value calculated for height has no apparent relationship to the actual height of the element.

This happens because the height is calculated when the resize window is created, but the sign window is resized from cookie settings between when the resize window is created and when it is used. So the values used for those settings are out of date.

Need to move the resize calculations to when the resize window is used, so that it relates to the actual size of the window rather than the initialized size.
