from svg to pdf it is not handling the shadows correctly, and all effects also

from svg to pdf it is not handling the shadows correctly, they lost in opacity and size , so some one need to check this and resolve it , and all effects also

Start by reproducing the reported SVG-to-PDF conversion with shadows and other effects, comparing opacity and rendered size with the source SVG. Trace the relevant CairoSVG conversion path and add regression coverage for the observed differences; done means shadows and effects retain the expected appearance in the generated PDF.
