Hi everyone, I wanted to let you know that I have added the new CSS3 background-position offsets support to WebKit.
This support is behind the ENABLE_CSS3_BACKGROUND feature define and it's disabled by default on all ports. I took the conservative approach despite it's a cool feature. Long story short, it allows you to specify three or four values to background-position. It's a nice addition as you can now position the images using length or values in relation to any of the four corners of elements, not just the top left corner. Opera, IE10 and Firefox implements this feature already (though the latter returns weird results using getComputedStyle). It is tracked by https://bugs.webkit.org/show_bug.cgi?id=37514 and the two patches landed (parsing and rendering) are http://trac.webkit.org/changeset/135632 and http://trac.webkit.org/changeset/136378. I believe the <position> type (3-4 values) could be/or is used in other cases so we can reuse the parsing code for four/three values if needed. I will investigate this afterwards and make appropriate patches. I plan to enable it by default on Qt and EFL ports this week. If somebody wants me to enable it on their ports please tell me, I'll be happy to do it. Looking forward to your comments.
