Computing CSS matrix3d transforms

Since no aliasing is applied (at least on Firefox), these transforms endup looking terrible and illegible.

A simple workaround is to render at double the size and then scale down in the same transform. Makes it edible in most non-ridiculous transforms.

Looks wonderful on Safari on my retina iPad mini :)

I was a bit disappointed that a library was used to solve the system of equations instead of going one step further using Cramer's Rule.

Otherwise, this was a fun read!

Nice!
