+
+ Implements an optimization to ignore fixed background images
+ (i.e. background-attachment: fixed) when a page does not contain
+ any fixed position elements so as to allow fast repaints (via bit
+ blit) when scrolling a page.
+
+ Currently, if a page has elements that specify either a fixed
+ background or a fixed position then we perform a slow repaint
+ (i.e disable blitting) so as to avoid rendering artifacts.
+ However, on low-powered/mobile devices slow repaints can cause
+ noticeable delays when scrolling a page with a fixed background
+ image. By sacrificing support for fixed background images when
+ there are no fixed elements on the page and with come care, we
+ don't need to force slow repaints and can avoid rendering artifacts.
+ Hence, on such devices we can improve the responsiveness of
+ scrolling a page with a fixed background image.
+
+ Note, this optimization is only enabled if the WebKit is built
+ with FAST_MOBILE_SCROLLING enabled.
+
+ Tests: fast/fast-mobile-scrolling/fixed-position-element.html
