[Mesa-dev] [PATCH 3/9] glx/dri3: Add additional check for gpu offloading case

[Axel Davy]

Checks blitImage is implemented.
Initially having the __DRIimageExtension extension
at version 9 at least meant blitImage was supported.
However some implementations do advertise version >= 9
without implementing it.
