hello,

here the "size" of a sketch in the draw() routine is different from the
one set in the setup handler, when running a sketch from the ide menu. but
width and height are the same in setup and draw, when calling the "present
sketch" menu item.

[code]
/* set then get display window size */
void setup()
{
background(255);
size (200, 200); // or P3D, OPENGL
println ("S: W="+width + " H=" + height);
noLoop();
}

void draw() {
println ("D: W="+width + " H=" + height);
}

void mouseDragged()
{
println ("M: W="+width + " H=" + height + " : X=" + mouseX + " Y=" + mouseY);
}
[/code]

results read:
S: W=200 H=200
D: W=200 H=200
D: W=210 H=207
M: W=210 H=207 : X=199 Y=198
M: W=210 H=207 : X=201 Y=200
M: W=210 H=207 : X=229 Y=225
M: W=210 H=207 : X=264 Y=256

notice, there are two lines from the draw routine. (this also shows, one
can drag the mouse outside of the window, and still get coordinates, even
negative ones, not a bug.)

finally managed to get this to replicate. will be looking for a fix.
