PDFBOX-4916: don't create new arrays when scaling/translating matrices

> possible
> ----------------------------------------------------------------------------------

> Project: PDFBox
> Issue Type: Improvement
> Components: Text extraction

> Reporter: Alfred
> Assignee: Andreas Lehmkühler
> Priority: Minor
> Attachments: PDFBOX-4916.patch

> LegacyPDFStreamEngine does translating and scaling using the generic
> concatenate matrix ops.
> A scale or a translate require much less multiplications and so there's room
> to improve there.
> I have the code ready and I will submit a patch right away.
