This commit adds ImageBuffer support to the OpenVG graphics backend. Not including Yong's toDataURL() implementation yet, that one is still subject to bug 37117 before I can use it here.

Not sure about our policy on define's. Don't we use static constants here?
+ void transformColorSpace(const Vector<int>& lookUpTable);
OpenVG doesn't need transformColorSpace. It is used to transform the colorSpace of an ImageBuffer from linearRGB to sRGB (DeviceRGB) and back. OpenVG can do that itself. We also don't transform an ImageBuffer after it is created (or at least it's not the intention of this method).
+ m_format = VG_sARGB_8888_PRE; break;
Newlines after ';'.
+ rect.x(), rect.y(), rect.width(), rect.height());
line up with 'data' please. Think I saw this before. Please fix it everywhere.
