[Sugar-devel] WebKit2 Browse - Download and Test

[Tony Anderson]

Hi Sam

The goal of Utkarsh's project is to integrate Richa Sehgal's GSOC work 
with Browse. This was the original goal but at the time Gonzalo was not 
available.
Ideally, an integration with 158 would save a step, I think it would not 
be helpful to use a development project to test webkit2. This is a 
critical feature because the webkit in 157.2 does not support flex - an 
essential feature in specifying layout for reponsive design. This is 
particularly important because browsers mistreat the Sugar screen 
resulting in poor matches between activities on an XO and the same 
activity on other laptops.

Previous versions of webkit, so far as I know, followed the W3C 
guidelines for partial implementation of html5 and css3 - as Internet 
Explorer famously did not.
