Yeah, change it to (void)drawSelf (the standard method declaration as 
used in Raster), and it will also work.
The ambiguous type signatures for the drawSelf method confuses the Tk 
callbacks (to Objective C) for redrawing newly exposed content of 
rasters.  So tclobjc pulls this method signature (instead of the void 
return one) and sets up the call to expect a return object when the 
function actually does not do that.  Badness ensues.. 

In other words, this definition pollutes the method signature database, 
which happens to be essential in this case.
Why an observed change relative to 2.1.1 occurred (is that what you're 
saying?) I didn't run down, but it might be switching from bug 
workaround code in FCall for the compiler to standard compiler idioms.  
In some sense, this `should' break.
