This try uses full 3D renderers working on the same ZBuffer target, but are capable to render one stripe per thread. This is rougher in granularity and uses multiple cores better than the first try (see gerrit 24393) which was too fine-granular being based on scanline render parallelization. SecUred some more classes based on SdrPrimitive3D for multi- theaded usage (places where local buffered stuff is done) Change-Id: I4ddd5885ad41dd6432d0695e528818a86e427bfd Reviewed-on: https://gerrit.libreoffice.org/24538 Tested-by: Jenkins <ci@libreoffice.org> Reviewed-by: Noel Grandin <noelgrandin@gmail.com> Reviewed-by: Armin Le Grand <Armin.Le.Grand@cib.de>
