[Mesa-dev] [PATCH 4/5] dri2: add DRI image offset to base bo.

[Gwenole Beauchesne]

Add offset argument to createImageFromName2() so that to notify the
driver to wrap the DRM buffer at the specified offset. This is useful
to wrap a DRM buffer describing a YUV picture into several other
images/textures mapping individual Y/U/V components.
