##### cairoMatrixMultiply

Multiplies the affine transformations in `a`

and `b`

together
and stores the result in `result`

. The effect of the resulting
transformation is to first apply the transformation in `a`

to the
coordinates and then apply the transformation in `b`

to the
coordinates.

##### Usage

`cairoMatrixMultiply(result, a, b)`

##### Arguments

`result`

- [
`CairoMatrix`

] a`CairoMatrix`

in which to store the result `a`

- [
`CairoMatrix`

] a`CairoMatrix`

`b`

] a`CairoMatrix`

##### Details

It is allowable for `result`

to be identical to either `a`

or `b`

.
