The tiny subset of numerical linear algebra that is relevant for 
graphics (mostly very basic operations, 2,3 or 4 dimensions) is 
not at all representative of the whole. The algorithms are 
different and the APIs are often necessarily different.

Even just considering scale, no one sane calls in to BLAS to 
multiply a 3*3 matrix by a 3 element vector, simultaneously no 
one sane *doesn't* call in to BLAS or an equivalent to multiply 
two 500*500 matrices.
