FIX "curved text" export in SVG2PDF: wrong degrees/position
"curved text" export in SVG2PDF, even if "Export PRO" feature is enabled, this is not fully supported: https://support.fancyproductdesigner.com/support/solutions/articles/13000103311-export-methods-explained
Actually it works,but not well: this is because the output has wrong degrees or wrong position.
Thank you
Right now curved text is only supported in node canvas export method.
In fact I proposed it as enhanced feature
