[Cuis] 2 new updates: Fix Morphic Slowdown and Disable new Profiler on old VMs

[Juan Vuletich]

Hi Folks,

I've just published 2 new updates and an updated image.

The first one is a slowdown when opening and resizing windows that I 
introduced by mistake in 4.1. It was found by Tim Rowledge while testing 
on the Raspberry PI (you can see squeak-dev for details). At first I 
thought it was a consequence of the new Float local coordinates, but it 
turns out that it was just a bug.

The second one is to disable the new and much better 
AndreasSystemProfiler if running on an old VM that doesn't include the 
new primitives. BTW, it seems that none of the VMs referenced from 
squeakVM.org includes them. For the performance issue, I wanted to 
profile code with a Stack-VM (i.e. a non-Cog VM). I could not find a 
Stack-VM that includes them for Mac or Windows. Does anybody know if 
such thing exists in binary form?

Cheers,
Juan Vuletich
