[Bf-committers] High level Mathutils additions

[Campbell J Barton]

Hi, there are a number of math functions I find myself using a but, that 
Id like to add into mathutils
Mathutils.TriArea(vec1, vec2, vec3)
- This would operate on 2d or 3d Vectors.

Mathutils.TriNormal(vec1, vec2, vec3)
- Return a unit length normal vector from 3 vectors - 3d only.

Mathutils.LineIntersect(vecA, vecB, vecX, vecY)
- works on a 2d or 3d vector, returns the intersection point or None if 
the line does not intersect.

Make it possible to multiple a 3d vector by a 4x4 matrix, at the moment 
you need to resize the vector to 4d and then do it-
this messes up Blenders internal state when you resize v.co to 4d- so 
you need to make a copy which is also annoying.

Any ojections?
- Cam
