I don't know if hasDimensionProps is worth it

Description
#9851 (comment)
curris always defined inmultiplyTransformMatrixArray. It should beundefinedso that the condition inside the reduce cb takes affect. Since it wasn't the multiplication was executed many redundant times.This has been found by @jiayihu and @asturur in #9851
It caused a perf hit and now we understand why
I am to blame!
closes #9851
In addition I have exposed
hasDimensionMatrixPropsto skipcalcDimensionsMatrixcalculation but from analyzing the code I don't see and real benefit. Instead of callingcreateScaleMatrix(1, 1)and doing 3 iterations over the matrix array it will callhasDimensionMatrixPropsand concat iMatrix.So maybe it better and maybe not.
