Description
The documentation of QPainter::CompositionMode_Plus says "Both the alpha and color of the source and destination pixels are added together."
When using an image with a FP pixel format, the colors seem to be added and even go beyond the 0-1 range, but the alpha isn't (it's capped at 1.0).
Is this the expected behavior?
