tdf#109340 Improve performance by reducing matrix multiplication
Multiplication of two B2DHomMatrix with operator* is very CPU expensive,
because 24 of double-precision floating point multiplication
needs to be performed.
With this patch I have reduced Multiplication of matrix,
by creating combined Scale and Transform matrix at once.
It allows to reduce matrix multiplication by one,
and improve import time.
