  30. //ok I just realized bruh did an obnoxious thing, and made all the shape functions take arguments in different patterns.
  31. //function( psvg, x,y, height, width, radius, fill, stroke, strokewidth )
  32. //Ill fix that later, RN gonna make animation work.

  34. /*I too did an anoying thing and wrote animateRotate using the format of the former args patterns.
  35.  * Using stdarg.h, functions require specifying the number of args for a function, these are as follows
  36.  *
  37.  * svg_ellipse: 8
  38.  * svg_polygon 8
  39.  * svg_text 8
  40.  * svg_line 7
  41.  * svg_rectangle 10
  42.  *
  43.  * after which, args are passed to the animateRotate function

  45.  * Example animateRotate call:
