Resolves #7777
When looping through images to create a GIF image, the frames may be different sizes.
At the moment, this means that
Pillow/src/PIL/GifImagePlugin.py
Line 671 in 1b67239
fillcomes from the size of the new frame, whereasmaskcomes fromImageChops.subtract_modulo()between the new and the old frame.This may cause a mismatch in size between the image being pasted and the mask, which can lead to an error.
