Fixed the resize bug where the image size lagged behind the window size by one frame.
Merge branch 'imagePipeline' of https://github.com/CarVac/filmulator-gui into imagePipeline
Enabled fullscreen mode. For now it's just with F11; there's no button yet because I have no clue where to put one.
Fixed fullscreen
Renamed the whole project from Filmulator-Testing-2 to filmulator-gui
Updated the readme to be more descriptive and to describe the current state of the program.
Reworded readme a bit. Well, a lot.

I added a "Using Filmulator" section.
