Not approved. This doesn't fix components/demos/house.lzx when I remove
the quotes from around the gradient string values. I checked, and the
'gradient-fill' attribute is type 'string'...

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.
