I do a lot of computational geometry, and so I often use eigen for the bigger/fancier linear algebra operations. This means that I don;t use things like glm, because it would make me spend a lot of time converting back and fort between eigen and whatever other linalg library.

However, the eigen dense header is bloated and uses about 40% of my compile time atm, more than any other file.

I know that 80% of the time the only eigen types I am using are vec2-4's and mat2-4's.

To speed up compilation time I want to include only those types and nothing else. Is it possible?
