Milestone Qt 4.6.2

Key goals:

• Upgrade the source tree to version 4.6.1 from the vendor.
• Add printer support.
• Add dummy accessibility support.

Slightly moved forward due to more features we decided to have in the 4.6.1 release.

Since Qt released 4.6.2 in the meantime, we decided to update to it before the release to stay on the edge.

Postponed to give it better testing. There is a lot of new code, webkit is the major update for the OS/2 version which is a handy piece of software.

Postponed two months due to priority change.
