This project is a version of Paint but in Pharo and using Bloc, Toplo and Coypul elements.
PaintInterface new openRectangle and circle size is defined by 0@0 extent: our position in drag and drop for an unknown reason (Must be to find) so I need to check it. Fill bucket is long when it's a large amount of pixel, we need a mapColor: aListOfPoint to: newColor such as the mapColor in FormCanvas which do it for each pixel from a color to a new color. Layers aren't finish yet so it still buggy.
