[Mesa-dev] [PATCH] i965: Set dirty bit for NOS fragment shader change

[Mike Stroyan]

A fragment program can change because of Non-Orthogonal-State changes.
brw_update_texture_surfaces needs to run because of changed surface offsets.
Set BRW_NEW_FRAGMENT_PROGRAM dirty bit in brw_upload_wm_prog to signal that.
