Better matrix animations Edit #182

Came across this matrix interpolation while reading up on matrices as implemented in Flash 8. Worth checking out to see if it cleans up some of the current transformation issues (e.g. Rects)?

// from http://www.readability.com/read?url=http%3A//www.senocular.com/flash/tutorials/transformmatrix/
function matrixInterpolate(m1, m2, t){
    var mi = new flash.geom.Matrix();
    mi.a = m1.a + (m2.a - m1.a)*t;
    mi.b = m1.b + (m2.b - m1.b)*t;
    mi.c = m1.c + (m2.c - m1.c)*t;
    mi.d = m1.d + (m2.d - m1.d)*t;
    mi.tx = m1.tx + (m2.tx - m1.tx)*t;
    mi.ty = m1.ty + (m2.ty - m1.ty)*t;
    return mi;
}
