+There must be a separate canvas for the dynamically created objects as some mechanisms in PD
+(like copy/cut/paste) get confused otherwise.
+On the other hand it seems to be possible to create objects without a canvas. 
+They won't receive DSP processing, though, hence it's only possible for message objects.
+Problems arise when an object is not yet loaded... the canvas environment is then needed to
+load it.. if there is no canvas, PD currently crashes.
+
+
+How to create the canvas:
+1) via direct call to canvas_new()
+2) a message to pd_canvasmaker
+	con: does not return a pointer for the created canvas
+
+There are two possibilities for the canvas
+1) make a sub canvas to the one where dyn~ resides:
+	pro: no problems with environment (abstractions are found and loaded correctly)
+2) make a root canvas:
+	pro: it will be in the canvas list per default, hence DSP is processed
+	con: canvas environment must be created manually 
+			(is normally done by pd_canvasmaker if there is a directory set, which is again done somewhere else)
+
+Enabling DSP on the subcanvas
+1) send it a "dsp" message (see rabin~ by K.Czaja)... but, which signal vector should be taken?
+	-> answer: NONE!  (just send NULL)
+2) add it to the list of _root_ canvases (these will be DSP-processed per default)
+	(for this the canvas_addtolist and canvas_takefromlist functions are used)
+	however, it's not clear if this can lead to problems since it is no root-canvas!
+
+In all cases the 1)s have been chosen as the cleaner solution
