Reviewed by Darin Adler.
As r155429 introduced ELEMENT_TYPE_CASTS, CSS_VALUE_TYPE_CASTS can be used
by css value type casting as well. This type cast macros will help to detect
bad-cast bugs as well as improve a code readibility.
This patch adds the following methods,
- CSSFooValue* toCSSFooValue(CSSValue*)
- const CSSFooValue* toCSSFooValue(const CSSValue*)
This patch support CSSImageSetValue and CSSReflectValue first. Other CSS*Values
will use this macro step by step.
Besides this patch will remove unnecessary local variables.
No new tests, no behavior change.
