Table-based transformations (will revert immediately)

This commit changes transformations to being based on a lookup
table intead of a big switch. This is something I had planned for a long
time and the code is nicer with this change. But unfortunately the performance
is noticeably worse, so I'll revert all these changes in the next commit.
I wanted to push this anyway so we can keep track of this.
