[Mesa-dev] [PATCH 1/8] dri: add putImageShm and getImageShm to swrastLoader

[Dave Airlie]

From: Marc-André Lureau <marcandre.lureau at gmail.com>

Add new API to put and get an image using shared memory. Instead of only
passing the data pointer, 3 arguments are given: the shmid, the data
offset and the shmaddr.

Bump interface version.
