Calculate the cover rect of tiled backing store with the trajectory vector.
https://bugs.webkit.org/show_bug.cgi?id=83462
Patch by JungJik Lee <[email protected]> on 2012-04-12
Reviewed by Kenneth Rohde Christiansen.
When trajectory vector is not zero, it is able to calculate the proper cover area.
No new tests - no new functionality.
