CTRL+V not posting 22 in P2D/P3D as it does in the default renderer

Created by: trackme518

Hi,
normally you can detect CTRL+V as a key==22 (ASCII) inside keyPressed(){} callback. However with P3D renderer this does not work. It also affects other combinations such as CTRL+Z and others.

Minimal code to reproduce the issue:

void setup() {
  //size(640, 480 ); //WORKS 
  size(640, 480, P3D); //DOES NOT WORK
}

int val = 0;

void draw() {
  background(val);
  val = 0;
}

void keyPressed() {
  if (key == 22 ) { //ASCII
    println("ctrl+v");
    val = 255;
  }
}

从 issue 中的最小 sketch 开始，比较使用默认 renderer 和 P3D 时 keyPressed() 的行为，重点关注 CTRL+V (key 22) 和 CTRL+Z。跟踪 renderer 特定的键盘输入路径，以确定这些组合在哪些位置出现差异。当这些组合在 P2D/P3D 中能够像在默认 renderer 中一样被一致检测到时，即表示完成。
