saveShape() for PShape

[Tacodiva]

It would be nice if there was a way to save a PShape that has been created/changed. I mean you already have a load shape (https://processing.org/reference/loadShape_.html) but, a load function goes hand in hand with a save function and you only have on!

PS, I realize that there is no obvious file format to save a PShape as but, where creative!
(well I hope you are)

@Ttacodude7729 I am sure patches for this are welcome... you find PShape.java here, and the derived PShapeSVG.java file here.

@gohai What file is the return value coming from for the loadShape function (here on line 11525) Thanks! 👍

Reference:

• PShape loads SVG, so one method would be to save some defined, loadable subset SVG - but the spec is huge : http://www.w3.org/TR/SVG11/
• Geomerative is a library with SVG save support: http://www.ricardmarxer.com/geomerative/
• Past discussion: https://forum.processing.org/one/topic/export-svg.html

SVG currently only does 2D; there'd have to be a 3D .obj exporter as well (eventually). Then you've got to work out whether the shape is 2D or 3D. Currently PShape::is3D just gets set by the PGraphicsOpenGL method createShapeFamily/createShapeGroup based on whether the PGraphics itself is 2D or 3D, which isn't ideal, although the user could call set3D(false) themselves.
