Remove dependency on LayoutTypes.h from transformation code

[Emil A Eklund]

TransformationMatrix includes LayoutTypes.h which is in rendering, this is a layering violation and makes using the it outside of rendering complicated.

Grammar Levi says: This is a run on. Period or conjunction needed :p

We'll also have to change it not to use MAX_LAYOUT_UNIT...

I don't like the duplication of this code here and in LayoutTypes.h. Seems like if this is where this needs to live to prevent layering problems, we should eliminate the version in LayoutTypes.

We don't usually put whitespace here, and this could just be one line.

Ditto.

Ditto.
