Improve UnknownMx4DPointFloat::FUN_100040a0

This one was quite annoying and I didn't get it to match as well as I hoped, but I still think it is an improvement. I would greatly appreciate if someone else took a look as well.

I tried to match FUN_100040a0 to BETA10 and found a number of corrections there, bringing it up to 91.4 %. LEGO1 might be down to compiler entropy, but I am not sure.

One extremely annoying thing I noticed is that the BETA10 compilation depends on the names of variables, even if they are unused.

Is that what determines the stack order?

I didn't figure out the entire pattern so I can't say anything for certain, but I can say for sure that the mere act of renaming a variable did at least influence the stack order (I tried a couple of names for the variables I ultimately named a and b). I guess there are other factors on the stack order as well (like the scope of the variable, when and where are they first used, ...).

Looks good to me! I'll give it another look later this week but it's an improvement for sure
