pushMatrix() inside beginShape(): vertex() seems to ignore the rotation, or can't it be used
that way?

----------------------------------------------------

float rot = 0.0;

void draw ()
{
background(255);
translate( width/2, height/2 );
beginShape();
vertex(0,0);
for ( float rr = 0.0; rr < rot; rr +=0.01 ) {
pushMatrix();
rotate( rr );

// shouldn't these have the same effect?

vertex( 0, 20 );
//vertex( screenX(0,20)-(width/2), screenY(0,20)-(height/2) );

popMatrix();
}
endShape(CLOSE);

rot += 0.2;
}

----------------------------------------------------

the example should draw a pie-chart, uncomment the line with screenXY to see it.
