Qt Declarative 2d on i.MX7

Time for some updates on the Qt Declarative 2d project.

I have recently focused on changing the rendering mechanism to a custom frame buffer hitting solution. The heart of it is a ARM assembler routine for alpha blending that composes the the graphics on to the "window" backbuffer. The assembler runs in circles around Qt's drawImage,
which was the primary composing mechanism I used before the assembler routine.

I am also lucky to have a i.MX7 board for certifying Qt Declarative 2d on. It runs very nicely.

The rssnews demo running on the i.MX7 using Qt Declarative 2d with the new rendering engine:

If you have hardware that you would like that to be certified, please contact me at:
