Take fb->offset[0] into account when calculating the linear and tile x/y offsets.

For non-tiled surfaces fb->offset[0] is simply added to the linear byte offset.

For tiled surfaces treat fb->offsets[0] as a byte offset into the linearized view of the surface. So we end up converting fb->offsets[0] into additional x and y offsets.

Do you have code using a non-zero offsets[0]? At least for current code that would indicate some kind of problem... though hopefully we'll be adding planar support back again sometime soon.
