- added a new CompressedData type to love.image - added love.image.isCompressed(file or data) - love.graphics.newImage automatically tests for compression when loading a file - added love.graphics.isSupported strings for DXT, BC5, and BC7 Compressed textures meant to be used on the GPU offer huge performance gains when - loading the texture from a file - loading the texture from RAM to VRAM - loading mipmaps - rendering --HG-- branch : image-CompressedData
