Please handle SVG images internally as vector images. Currently, even in LL26, it seems that SVGs are rendered as bitmaps and then integrated into the preview or printed. So if I zoom deeply into the SVG graphic it gets pixeled and blurry. This is also a big problem, when using the new functionality to print posters!
But this would only be the first step. Next step has to be the export of SVG in PDFs as vectors: SVG: Export as vector graphic into PDF
