ASCII图画分类： 图像处理 可以将鼠标画的图象转成ASCII的形式

//Something that you can click on and select as a drawing tool
//Something that controls an AsciiDrawPanel (sets its color)
//This is similar to the paletteItem class.
//
//
// Each item has a certain pre-defined size.
// This carries an ICON which is just a description of where
// the pixels of the item's picture should be drawn.
// When selected, all white space is yellow.
