* the property's value, along with possibly some leading whitespace
|
|
* and trailing text like "!important", and possibly a ';' and/or
|
|
* '}' (along with any other bogus text the author happens to
|
|
* include before those, which will probably make the decl invalid).

|
|
* convert the property to a known unprefixed equivalent, and we also
|
|
* performed any known-to-be-necessary fixup on the value, and we put
|
|
* the result in aUnprefixedDecl.
|
|
* Otherwise, this function returns false.
