Added love.math.compress(data, format [, level]) and love.math.decompress(compresseddata) / love.math.decompress(compressedstring, format).

Browse Source 
Renamed the love.image CompressedData type to CompressedImageData.

love.math.compress returns a love.math CompressedData object which holds the newly compressed data. Currently supported formats are "lz4" and "zlib". Note that the formats are not file formats and don't compress filesystem hierarchies.
