2018-02-01Convert CFX_CSSPropertyTable to CFX_CSSDataRyan Harrison
This converts the existing class naming and references. The ::Entry struct is converted to ::Property. The GetBy* methods are renamed to GetPropertyBy*. Free functions from other parts of the CSS code base are merged into the class. GetCSSPropertyValueByName becomes ::GetPropertyValueByName with a return value of ::PropertyValue*. GetCSSLengthUnitByName becomes ::GetLengthUnitByName with a return value of ::LengthUnit*. GetCSSColorByName becomes ::GetColorByName with a return value of ::Color*.
