* Implement OpenVG buffer scrolling and enable it on Symbian.Jason Barron2010-04-141-0/+6
| | | | | | | | | | | | | | | Add support for accelerated scrolling in the "direct" window surface implementation. Using vgCopyPixels(), the already rasterized content on the surface can be shifted to a new location such that only a portion of the suqsequent frame needs to be repainted instead of the entire frame. This only works when the "preserved" EGL swap behavior is enabled and the impact on performance is highly dependant on the specific hardware platform in use.
