GPU provides no performance improvement for fillSolidRect() for rectangles >= 500 x 900

My hardware is imx6 quad running Windows CE7 = WEC7 = Windows Embedded Compact 7.

I turn on the GPU and I see performance gains for small rectangles up to 500 x 900.

For larger rectangles, there is no performance improvement. See graph.

This appears to be a bug since many displays have much higher resolutions.

It seems the GPU software stack should, if necessary, break the problem down into chunks if 500 x 1000 is too big.
