Thanks all for the detailed replies. I wasn't aware of the distinction made between points and vectors for the purposes transforms. However, if I understand things correctly, introducing a vector type could be considered separately from the issue I initially raised.
It seems that everyone is agreed that xxxSize should be used only when you really want to represent a size. A good first step would be trying to enforce this, such that all points and vectors are represented with xxxPoint. As Shawn points out, when doing this, we need to make sure that we continue to use the correct homogeneous coordinate for transforms. Removing the existing subtraction operator (xxxPoint minus xxxPoint returns xxxSize) might be a good place to start. Introducing the concept of a vector could then be done in a second phase. WDYT?
