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.

#  EMSCRIPTEN_FOUND       - system has Clang
#  EMSCRIPTEN_VERSION     - Clang version
