API: Optimize @keyframes to use from/to format

[codeworksdev]

Every @keyframe included in the standard distribution package has been optimized to use from/to syntax vs. 0%/100% syntax. This provides better compatibility with some older devices and platforms.

EXAMPLE

#a.keyframes(
    rotateInUpRight; {
        from {
            #a._transform-origin(right bottom);
            #a._transform(rotate3d(0, 0, 1, -90deg));
            opacity: 0;
            }

        to {
            #a._transform-origin(right bottom);
            #a._transform(translate3d(0, 0, 0));
            opacity: 1;
            }
        }
    );
