hmmm ok, ill try that
also see Off-screen render performance, multiple PGraphics objects and Shared PGraphics instances - drawing
but ummmm… how would i go about seperation? as canvas.fill(0); in an application would fill the canvas in ALL applications since it is shared, right? if so, could i use PGraphics.clip(x1, y1, x2, y2) to implement a global drawing canvas?
