Update

Current build:

• Full working (... ish)
  - Loading IFF image (drag and drop file on app works too) (Only IFF supported at this time)
  - Zoom (Mouse wheel)
  - Grid (right mouse button to set and mouse to drag out the grid)
  - Saving Copper (colors)
  - Saving Raw Normal/Blit works. 

• Partly:
  - Grid saving only works on Raw Normal  (partly -> Width) .  Width needs to be the full width. You can define the height as you like.
