Description: ------------ Reproduce: To test resize image containing solid white background. After resize pixels with color different from #FFFFFF will appear. Probable cause: gdImageSetPixel parameters (red, green, blue, alpha) are casted to int in gdImageCopyResampled which cause them to floor so 254.9999999 became 254 instead of 255.
