Apart from the fact that EulerAngles are quite useless for real work I
can understand that beginners usually want them to get a quick start...

Generally it's best to keep the libaray as small and generic as possible.

So I'd offer only one function that generates the rotation matrix. This
function should have a fixed order (that's identical to OpenGL -
although I didn't find a gl, glu or glut function that uses euler
angles...).

If the user wants a left or a right multiplication is totally up to him,
so the library should try to be smarter :)

CU,
Christian
