Transformation translation was rounded, leading to jumpiness in some cases.

This issue has been resolved.
In Dream Seeker, translation is not rounded to integers, and it just appears to use anti-aliasing or super-sampling (whatever the word is) to approximate the pixels.

In the Web Client, the translation is rounded to integers, causing a tiny bit of jumpiness that wasn't originally there. This is most apparent when slowly rotating an object around a non-center point, like the guns in shootah in space. The gun will rotate a tiny bit before moving.

Rotation isn't rounded and the pixels are placed very accurately and smoothly.

Dang. I left translation out of the transform matrix so we could save some network space, but I hadn't thought about the jumpiness.
