I'm not troubled by it where the different versions of SoaS are built on
different versions of operating system components; fonts, rendering
libraries, Xorg drivers, GTK+, and so forth.  Each of these components
contributes to the eventual result.

If you can show that all these components are the same, yet a rendering
differs, then perhaps it is part of Sugar that is doing it, and it could
be investigated.  But I think it is unlikely to be Sugar.

Since there are so many variables in the calculation, an activity author
should presume that the size requested may not occur, or that the size
observed on one platform won't be the size observed on another platform.

Perhaps you could make a small test activity that asks the toolkits to
render some text, then measure the result, and gather some information
about the cause of the differences.
