Ensure that the checkForSolidColor() optimization is correctly triggered
for all cases of drawPattern. Currently, the optimization was not triggered
when the check had not been previously performed via a request for the
image's NativeImagePtr.
Implement the Qt version of the checkForSolidColor() method. Combined with
the bug fix this reduces the time it takes to draw a repeating background
of a 1x1 image from ~50msecs to ~0msecs on my machine.
