Dave Airlie 2b67657096 gallium/swrast: fix front buffer blitting. (v2) ... So I've known this was broken before, cogl has a workaround for it from what I know, but with the gallium based swrast drivers BlitFramebuffer from back to front or vice-versa was pretty broken. The legacy swrast driver tracks when a front buffer is used and does the get/put images when it is mapped/unmapped, so this patch attempts to add the same functionality to the gallium drivers. It creates a new context interface to denote when a front buffer is being created, and passes a private pointer to it, this pointer is then used to decide on map/unmap if the contents should be updated from the real frontbuffer using get/put image. This is primarily to make gtk's gl code work, the only thing I've tested so far is the glarea test from https://github.com/ebassi/glarea-example.git v2: bump extension version, check extension version before calling get image.
