Ok, this is soluble.
All setting of CSS attributes should be through LzSprite. LzSprite
has to convert LFC numbers using CSSDimension (q.v.) because CSS
dimensions are strings and must have units (unless they are 0).
CSSDimension could be conditionalized for browsers using the Jim/Max
capability scheme. And it can turn NaN back to undefined or null or
0 or whatever makes i.e., happy.
Of course, we probably should not be wasting time animating undefined
properties, either.
