Chrome will improve how CSS transforms are handled to reduce cases where a matrix interpolation fallback is used. An interpolation is an intermediate transformation. Sometimes interpretation of the CSS rule requires falling back to a matrix to accomplish the interpolation, and this can produce visual results other than what the web developer intends. To mitigate this, the spec was changed to reduce the number of situations when this can occur.
