Re: [Cin] oops apparently 'subtract' mode is broken!

I think the problem is due to the alpha channel present in the image. It is imported inside CinGG by removing the transparency and converting it to white. See attached image. I lose transparency with both png and exr, so it is a problem with CinGG (or me getting something wrong) and not the images. I have been using the RGBA-FLOAT color model. A long time ago it seems to me that there was talk of problems with importing sources with alpha channel, but I can't find it again.
