My experience with doing CSS-based bar graphs showed that calculating 
pixels as floating point values and rounding them to integers at the 
last possible moment worked best. If you use integers to do complex 
calculations you are sure to end up with aliasing problems.

I would imagine many renderers work like this already, as we would 
probably end up with overlapping and/or gaps in fluid layouts otherwise.
