Incorrect rendering after save/reload

[ungureanuliviu]

I'm working on a small app where you can prepare a design (curved text included) on fronted which will be rendered later with nodejs.

First, thank you for the library: it is really really useful.

I noticed one small bug: The curved text is not rendered correctly after you call canvas.toJSON() and canvas.loadFromJSON() if the radius or spacing got updated.

Steps to reproduce:

• Create a CurvedText (radius=100)
• Update the radius to 150
• canvas.toJSON()
• canvas.loadFromJSON()
• You will notice that the position of the first rendered letter is not the same as it was before saving.
