Make lowest line of Splash image frames transparent to work around scaling issues The Splash image is scaled. Sometimes, the lowest line is repeated on the top, which caused some weird lines to appear above big splashes (e.g. piano). This has been done fully automated with a script. Only the alpha channel was changed. The color information is preserved.

# This file is used by EnableLanguage in cmGlobalGenerator to determine that

# If not, a fatal error is set, cmake stops processing commands and will not
# generate any makefiles or projects.
