This looks sensible, but is not described in the ChangeLog.

We could get rid of the ifdefs by using the extensions supported by GraphicsContext3D. The patch changes it so that GraphicsContext3DPrivate uses the framebufferblit extension supported by Extensions3D. Currently, we dont support antialiasing with GLES (i.e GraphicsContext3d::validateAttributes).

pleae try to keep these lines a bit shorter... or at least the same length
