Squeak port to Amiga progress 6-10

Hello Everyone,

As of today I have speedy bitmap display working correctly, through the 
use of the Amiga system's native WriteChunkyPixels() function and 
built-in clipping functionality of the layers library.  Mouse clicking 
works and windows can be moved around successfully, scroll-bars scroll, 
text can be selected.


Alas, the colors are wrong, as I have not yet done any color mapping.  
I also seem to be stuck to 8-bit depths with this 2.3 VM, which is 
strange, but may make my life easier right now.  (I believe that the 
Amiga's graphics system will automatically handle writing different 
bit-depths to any depth screen, which would be nice.  I am crossing my 
fingers.  I have been able to use this 8-bit display on 8-bit and 
15-bit displays with no changed code).

A sticking point right now is noticeable on the current screenshot.  
After the image has loaded with its initial project setup, any 
newly-opened windows (browser, transcript, or zooming any of the Play 
With Me's) causes two window gadgets to appear, but no actual window.  
Nicely, PopUpMenus work great.  I am at a loss.

Also I have not yet dug deeply into the file code.  I have a feeling my 
directory delineators will not work, as the Amiga uses a combination of 
:'s and /'s;  i.e. "DH0:Development/Squeak/SqueakVM".  Why this would 
keep a browser from opening, I am not sure.

Thanks everyone for your help so far.  This is turning out to be quite 
the adventure.

Tim J.
