I THINK IT'S DONE!?

Worked all weekend on it. I don't know what else I'd add to it at this point. 

Here's where we are:

• Added Mac and Linux support 
• Editing is all done with the keyboard. No mouse required!
• Additional Editing capabilities
  • Add multiple images (up to 100!)
  • Per image Hue Shifting
  • Per Image Gain adjustment
  • Per Image Transparency adjustment
  • Per Image Chroma key compositing
  • Overall Brightness & White level adjustment
• Image input and output directories are stored.
• Image Loading Screen previews images.

See https://itch.io/t/1193818/how-do-i-use-this-thing for use instructions.

Thanks!
