[Mesa-dev] [PATCH V6 0/8] intel: add support for EGL_KHR_gl_image

[Abdiel Janulgue]

- Rename draw_x/y to tile_x/y in dri image struct. These are now used as 
  adjustment pixels from our stored aligned offset to the exported image
  instead of the entire x/y offset from the base address.
- Take into consideration the offset from our bo so that sub-image functions 
  resolves properly to the our original image. 
- Move mt->stencil_mt check out of misleading comment in 
  intel_setup_image_from_mipmap_tree
