tdf#101083 speed up SVG rendering with pattern fill
but cut and paste from the VclPixelProcessor2D to the CairoPixelProcessor2D code.
Which makes this SVG render in reasonable time when using the cairo backend.
We can probably do even better by cutting out the usage of VCL here, but this
is good enough for now.
