Bug 100835 – perspective-origin should ignore values with more then two lengths and use the default values

• Status: RESOLVED
• Resolution: FIXED
• Component: CSS

[Zoltan Nyul]

The perspective-origin now uses the first two values if there's more then two given (like -webkit-perspective-origin: 10% 20% 30%;) however transform-origin uses the default values, and also firefox is using the default values for perspective-origin with more than two values. The specification says only that it can have maximum 2 lengths (http://www.w3.org/TR/css3-transforms/#perspective-origin) but i think it makes sense to have the same behavior.
