Description
When drawing a scaled-up, ARGB32PM image on an RGB32/ARGB32PM target, without SmoothPixmapTransform, with source over composition, the image appears shifted to the right, as if the image pixels were sampled too far left. It also happens if the image is scaled up and rotated 180 degrees. The bug does not occur if opacity is less than 1, the image format is not ARGB32PM, the target format is not RGB32/ARGB32PM, SmoothPixmapTransform is enabled, transformation is different than the ones mentioned or if composition mode is not source over. The bug does not affect texture brushes.
