You're all welcome. ;)

I am not intimate with the development cycle and work-flow of the OLPC XO.  
I learned sufficiently to see it's Fedora Core-based, and that Sugar is  
becoming distro agnostic.

Thus, my answer is simply limited to my current usage of the XO. I want  
PaintWeb to work well on the OLPC XO-1 laptop, with the latest stable OS  
release (that's 8.2.1).

The modifications resulting from this work are already deployed into  
PaintWeb. You can try the last working SVN trunk snapshot at:

http://www.robodesign.ro/paintweb/trunk/src/paintweb.html

The paintweb.js file contains the updateCanvasScaling() function which  
does the Canvas scaling.

The application is working fine on the XO.


Best regards,
Mihai
