[PATCH 1/4] ui: Use allocated size instead of window size

[Alexander Orzechowski]

In these cases, we only care about the size of the virtual console
itself. Previously, these calculations were made using the size of
the entire window, which would include the size of the virtual console
plus all the ui elements around it.
