screenX etc. "broken" with pixelDensity(2) combined with JAVA2D renderer

Created by: clankill3r

The following code:

void setup() {
  size(600, 600, JAVA2D);
  pixelDensity(2);
  println(screenX(600, 0));
}

prints out 1200.

If I change the pixelDensity to 1 it prints out 600.

For P2D and P3D it will always be 600, no matter the pixelDensity (like it should be).

I compared the screenXImpl here are the results (not sure if this helps):

JAVA2D with pixelDensity 1

JAVA2D with pixelDensity 2

P2D with pixelDensity 1

P2D with pixelDensity 2

My first impression is that the pixelDensity 2 for JAVA2D is bit of a cheap hack. (But what do I know!).

Start by running the supplied sketch with the JAVA2D renderer and compare its screenXImpl behavior at pixelDensity 1 and 2 with the P2D results described in the issue. Trace the renderer-specific screenX path and verify that screenX(600, 0) reports 600 regardless of pixel density, while preserving the existing behavior for the other renderers.
