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.

# TestBigEndian
# -------------
#
# The TestBigEndian.cmake module that ships with CMake, which
# checks if the system is big endian or little endian, assumes
# that a binary is produced that will have bytes that correspond to the
# endianness on the target system. Since emscripten produces Javascript, we
# override the default behavior and always return little endian.
