Update magic wand icon.
Fix strange zoom code, it acts very counter-inuitive images with big height/width ratio.
Make flood fill/ magic wand preview to be xored and not connected to any specific color.
Fix "layers" controls updating on loading another image.
Add dispose to every createGraphics call in vain hope that it would help me somehow.
Apply some fixes from intellij analyzer.
Separate color distance for magic wand and flood fill. Make them stored in settings.
Add saving of selection action and fill opacity.
Finalize stuff, add some checkboxes, make some stuff saving.
