After discussion with Jernej, InnoSetup should now work better with rescaling a big image properly to the window size, yet the ratio should still matter. Apparently the welcome image is a hack and this is why it requires specific ratio images. We don't use the big size yet, but since Jernej told me which dimensions are expected, I already added the code for it to make it easier later. So anyway this code would allow us not to have to commit welcome images each time, which are basically resized copy in BMP of the splash screen, slowly yet surely filling up our repository with image duplicates. After all, we develop a scriptable image editor! We should use it to edit images and export in expected formats! I only use this script for the devel installer for now, for testing and see how it goes.
