curveVertex() causes OutOfMemory in P2D renderer

[Real-John-Cheung]

Description

curveVertex() causes java.lang.OutOfMemoryError: Java heap space error when the vertex amount is big in P2D render. With the default Java2D render it works fine.

void setup(){
  size(800,800, P2D);
  beginShape();
  for(int i = 0; i < 26000;i ++){ 
    curveVertex(i * 0.1, 100);
  }
  endShape();
}

Above sketch crashes due to OutOfMemoryError, below sketches can be executed without problem:

void setup(){
  size(800,800);
  beginShape();
  for(int i = 0; i < 26000;i ++){ 
    curveVertex(i * 0.1, 100);
  }
  endShape();
}

void setup(){
  size(800,800, P2D);
  beginShape();
  for(int i = 0; i < 2000;i ++){ 
    curveVertex(i * 0.1, 100);
  }
  endShape();
}

Possible Causes / Solutions

Might have something to do with how Catmull-Rom splines is calculated in P2D?
