PShape.scale not working with PShape.resetMatrix when P2D renderer is used

Description

PShape.scale does not play well with PShape.resetMatrix when P2D renderer is selected.

Expected Behavior

I believe this to be a bug. I expected the ellipse to be drawn and scaled up absolutely by 2. I tried other svg's (loadShape) and the problem still occurred.
Without P2D:

With P2D:

Current Behavior

The ellipse is not drawn at all. I think the issue lies within PShape.scale because PShape.translate seems to work fine, or possibly P2D and PShapeOpenGL.

Steps to Reproduce

PShape s;

void setup(){
  size(1000,1000,P2D); // Removing P2D allows it to work.
    s = createShape(ELLIPSE,0,0,100,100);
}


void draw(){
  background(0);
  translate(width/2,height/2);
  // s.translate(-200,100); This works!
  s.scale(2);
  shape(s,0,0);
  s.resetMatrix();
}

Hey there! Just a quick note that I believe I am seeing the same behavior on Processing 3. @protonlaser91, can you please confirm if you see this in Processing 3 as well?

@sampottinger Apologies for the late reply, but yes I do see this on Processing 3 too.

The ultimate cause for this issue was an error in an internal utility to invert the scaling transformation in 2D, #366. Long term fix is included in this PR
