I am currently simply trying to translate some of my processing programs to native openGL and have a simple problem which I still could not fix: When I try to draw a simple quad with a texture, the texture always does not texture the whole quad. Its propably a simple thing I just don't see right now. Here is the code. I first draw a filled quad and afterwards a textured one to see if they match. Apparently they dont:

import javax.media.opengl.*;
import javax.media.opengl.glu.*;
import com.sun.opengl.util.*;
import processing.opengl.*;
import java.nio.*;

PGraphicsOpenGL pgl;  // g may change
GL gl;  // always use the GL object returned by beginGL
GLU glu;

PImage test;
void setup() {
 size(640, 480, OPENGL);
 hint(ENABLE_OPENGL_4X_SMOOTH);
 colorMode(RGB, 1.0, 1.0, 1.0);
 pgl = (PGraphicsOpenGL) g;
 gl = pgl.beginGL();
 glu = ( (PGraphicsOpenGL) g ).glu;
 test = loadImage("test.jpg");
}

void draw(){
 background(0);
 pgl.beginGL();
 gl.glDisable(GL.GL_DEPTH_TEST);
 gl.glDepthMask(false);
 gl.glTranslatef(width/2, height/2, 0);
 gl.glBegin(GL.GL_QUADS);
 gl.glColor4f(1.0, 0.5, 1.0, 1.0);
 gl.glVertex2f (0.0, 0.0);
 gl.glVertex2f (frameCount, 0.0);
 gl.glVertex2f (frameCount, frameCount);
 gl.glVertex2f (0.0, frameCount);
 gl.glEnd();
 gl.glEnable(GL.GL_TEXTURE_2D);
 pgl.bindTexture(test);
 gl.glBegin(GL.GL_QUADS);
 gl.glTexCoord2f(0.0,0.0);
 gl.glVertex2f (0.0, 0.0);
 gl.glTexCoord2f(1.0,0.0);
 gl.glVertex2f (frameCount, 0.0);
 gl.glTexCoord2f(1.0,1.0);
 gl.glVertex2f (frameCount, frameCount);
 gl.glTexCoord2f(0.0,1.0);
 gl.glVertex2f (0.0, frameCount);
 gl.glEnd();
 gl.glDisable(GL.GL_TEXTURE_2D);
 gl.glEnable(GL.GL_DEPTH_TEST);
 pgl.endGL();
}
