Python implimentation of the transition from Doom.
Put background image in folder with name background.png and foreground image in folder with name foreground.png. Execute the python file and the output will be saved to out.gif.
Images must have same resolution. Both images must also have the same color mode (eg. RGB). Other file formats can be used (although I haven't added handling for them yet).
For best results, use original Doom resolution (320 x 200), otherwise change parameters in melting.py to better fit other resolutions.
