[Mesa-dev] [PATCH 4/5] __DRIimage: version 6, add new picture structure.

[Gwenole Beauchesne]

The addition in version 6 enables creating EGLImages with different picture
structure for supporting interlaced textures. The new flags are only valid
in createSubImage() format field. Should the driver support those, it should
report version as 6, and determe the underlying picture format by masking
out the picture structure flags.
