I agree, but unfortunately, there is no drawutils API to blend a colored
mask. It would be necessary to write one, and I do not want to spend too
much effort on this.

I could change the color pseudo-randomly between the squares instead of
making just a checkered pattern. Or I could blend random noise in red, then
green then blue in a random order (alpha blending does not commute). Any

Also: I agree that testsrc2 is not the best name ever, but I have no idea
what to make of it. It could be testsrc with an option to select the mode,
the default being the old mode (then printing a warning that the default
will change, then changing the default). Again, what do people prefer?
