There is still a lot of work needed to refactor it properly.
- use the Sutherland–Hodgman algorithm, with some minor changes
- made clipping more general, allowing clipping of any coordinate,
before and after division by w
- compute the z coordinate only at the fragment stage instead of each
time clipping creates / moves a vertex, in addition to the fragment
stage
- added VectorCoords to choose at compile-time different coordinates
based on a template argument
- added transpose struct to allow shuffling of vectors coordinates
- added math::utils::lerp which interpolate linearly a float
- added Vector{2,3,4}::map() which maps a vector from one range to
another
- added template parameter to DerivedVertex (and therefore
TriangleDerived) to allow choosing which dimension to use
