[Interest] Anti-Aliased line drawing.

[william.crocker at analog.com]

Hello:

I am slowly porting my app forward from Qt 4.8.6

With 4.8.6, it is my observation that simple line drawings,
as made by a QPainter and with Antialiasing enabled in render hints,
are implemented in software which makes them quite slow.

What can I look forward to if I port my app to 5.X (5.7)
Is there an option for hardware acceleration
of AA line drawing and how would I enable it.

I develop on RedHat Enterprise Linux 6.8

Thanks.

Bill
