Summary: Pass custom CSS property values as strings Bugs Fixed: LPP-9490 CSS Parser should default to delivering unknown attributes as strings to be presentation-type parsed at runtime Technical Reviewer: [email protected] (pending) QA Reviewer: [email protected] (pending) Release Notes: The CSS parser passes through most property values unchanged (but as strings, so they are valid Javascript). We only need a few special properties, e.g., the keyword `inherit` will be passed as a unique value, to distinguish from the string "inherit" (so if you wanted to specify the content of a node as the literal value "inherit", not have it inherit a value from it's parent). For backwards compatibility, color specifications are still canonicalized at compile-time and output them as hex numbers -- this may go away in the future. If you want a color specification to come through unparsed, you can use `rgba(...,...,...,1)`, because that will _not_ be converted at runtime. Any values that appear as "arguments" to a function (e.g., url(), rect(), linear-gradient()) will be passed straight through. The attribute's presentation type is invoked when the attribute is bound to a CSS property value; it's job is to convert that value to the appropriate internal representation. Overview: Rewrote the compile-time CSS parser to do nearly no compile-time conversion of property values, and to pass any custom (unknown) values through as strings, so the runtime can use the presentation type system to parse arbitrary values. Details: neighborhoodclasses, designerview: Fixed up the specification of some attributes to be more modern for testing. LzNode: Use acceptAttribute to install style property values. CSSHandler: Rewritten to do minimal compile-time processing.
